25 to 69 beats per minute Let x be a random variable that represents the resting heart rate for an adult horse Assume that x has a distribution that is approximately normal USE SALT a The empirical rule indicates that for a symmetric and bell shaped distribution approximately 95 of the data lies within two standard deviations of the mean 95 20 Therefore a 95 range of data values extending from 4 20 to 20 is often used for commonly occurring data values Note that the interval from 20 to 20 is 40 in length This leads to a rule of thumb for estimating the standard deviation from a 95 range of data values 20 Estimating the standard deviation For a symmetric bell shaped distribution standard deviation range high value low value where it is estimated that about 95 of the commonly occurring data values fall into this range Use this rule of thumb to estimate the standard deviation of x distribution in beats per minute 11 beats per minute b What is the probability that the heart rate is less than 29 beats per minute Round your answer to four decimal places 0 0505 c What is the probability that the heart rate is greater than 61 beats per minute Round your answer to four decimal places 0 10156 d What is the probability that the heart rate is between 29 and 61 beats per minute Round your answer to four decimal places e A horse whose resting heart rate is in the upper 10 of the probability distribution of heart rates may have a secondary infection or illness that needs to be treated What is the heart rate corresponding to the upper 10 cutoff point of the probability distribution Round your answer to the nearest whole number

simultaneously function as a side show for white people who look on with delight at all the differences that surround them We may be on our way to genuine hybridity multiplicity without white hegemony and it may be where we want to get to but we aren t there yet and we won t get there until we see whiteness see its power its particularity and limitedness put it in its place and end its rule This is why studying whiteness matters It is studying whiteness qua whiteness Attention is sometimes paid to white ethnicity e g Alba 1990 but this always means an identity based on cultural origins such as British Italian or Polish or Catholic or Jewish or Polish American Irish American Catholic American and so on These however are variations on white ethnicity though some are more securely white than others and the examination of them tends to lead away from a consideration of whiteness itself John Ibson 1981 in a discussion of research on white US ethnicity concludes that being say Polish Catholic or Irish may not be as important to white Americans as some might wish But being white is This then is why it is important to come to see whiteness For those in power in the West as long as whiteness is felt to be the human condition then it alone both defines normality and fully inhabits it As I suggested in my opening paragraphs the equation of being white with being human secures a position of power White people have power and believe that they think feel and act like and for all people white people unable to see their particularity cannot take account of other people s white people create the dominant images of the world and don t quite see that they thus construct the world in their own image white people set standards of humanity by which they are bound to succeed and others bound to fail Most of this is not done deliberately and maliciously there are enormous variations of power amongst white people to do with class gender and other factors goodwill is not unheard of in white people s engagement with others White power nonetheless reproduces itself regardless of in tention power differences and goodwill and overwhelmingly because it is not seen as whiteness but as normal White people need to learn to see themselves as white to see their particularity In other words whiteness needs to be made strange NOTES 1 I use the terms race and racial in this opening

characters blackness but also feel that you just think of them as people in other words that they don t only speak for their race Jhally and Lewis argue that this is achieved by the way the family conforms to the everyday generic world of white television 1992 100 an essen tially middle class world The family is ordinary despite being black because it is upwardly mobile it can be accepted as ordinary in a way that marginalises most actual African Americans If the realities of African American experience were in cluded then the characters would not be perceived as just people 3 See for instance Bogle 1973 Hartmann and Husband 1974 Troyna 1981 MacDonald 1983 Wilson and Guti rez 1985 van Dijk 1987 Jhally and Lewis 1992 58ff Ross 1995 The research findings are generally cast the other way round in terms of non white under representation textual marginalisation and positioning as deviant or a problem Recent research in the US does suggest that African Americans but not other racially marginalised groups have become more repre sented in the media even in excess of their proportion of the population However this number still falls off if one focuses on central characters 4 The Crying Game GB 1992 seems to me to be an example of this It ex plores with fascination and generosity the hybrid and fluid nature of identity gender race national belonging sexuality Yet all of this revolves around a be mused but ultimately unchallenged straight white man it reinscribes the post tion of those at the intersection of heterosexuality maleness and whiteness as that of the one
