Assume that the sample is a simple random sample obtained from a normally distributed population of IQ scores of statistics professors Use the table below to find the minimum sample size needed to be 99 confident that the sample standard deviation s is within 1 of o Is this sample size practical 6 To be 95 confident that s is within of the value of o the sample size In should be at least To be 99 confident that s is within of the value of o the sample size In should be at least The minimum sample size needed is Is this sample size practical 1 5 10 20 30 40 50 OC Yes because 19 205 768 192 48 21 12 8 1 5 10 20 30 40 50 33 218 1 336 336 85 38 22 14 OA Yes because the sample size should be as large as possible for most applications OB No because the sample size is excessively large to be practical for most applications the sample size is small enough to be practical for most applications O D No because the sample size should be as small as possible for most applications
