Determine the Type I error if the null hypothesis Ho is the percentage of homes in the city that are not up to the current electric codes is no more than 10 And the alternative hypothesis Ha is the percentage of homes in the city that are not up to the current electric codes is more than 10 Select the correct answer below O There is insufficient evidence to conclude that more than 10 of homes in the city are not up to the current electrical codes when in fact there are more than 10 that are not up to the current electric codes There is insufficient evidence to conclude that less than 10 of homes in the city are not up to the current electrical codes when in fact there are less than 10 that are not up to the current electric codes There is sufficient evidence to conclude that more than 10 of homes in the city are not up to the current electrical codes when in fact there are no more than 10 that are not up to the current electric codes There is sufficient evidence to conclude that less than 10 of homes in the city are not up to the current electrical codes when in fact there are at least 10 that are not up to the current electric codes FEEDBACK MORE INSTRUCTION SUBMIT

mosquito repellent claims that it will effectively repel mosquitoes for at least 6 hours A local biologist thinks that the company s claim is exaggerated and the length of time for which this brand of mosquito repellent is effective is actually less than 6 hours To test her hypothesis the biologist devised a randomized sample of 107 trials and found that the mosquito repellent was effective for 5 61 hours on average Use the p value method to test the hypothesis that the mean effective length of time of this brand mosquito repellent is less than 6 hours using a significance level of 2 5 Assume the standard deviation of the distribution of all times for which this brand of mosquito repellent is effective is known to be 1 76 hours State the null and alternative hypothesis for this test OH 6 H p 6 O Ho p 6 H p6 OH 6 H p 6 O Ho 6 H p 6 Determine the test statistic for the hypothesis test 0 1 82 0 2 29 0 0 32 0 1 07 Determine the p value for the hypothesis test 00 0110 00 9890 00 2194 00 0374 Determine the appropriate conclusion for this hypothesis test O The sample data provide sufficient evidence to reject the alternative hypothesis that this brand of mosquito repellent is effective for less than 6 hours on average and thus we conclude that the company s claim that the mosquito repellent is effective for at least 6 hours is likely true O The sample data do not provide sufficient evidence to reject the null hypothesis that this brand of mosquito repellent is effective for at least 6 hours and thus we conclude that the company s claim that that the mosquito repellent lasts for at least 6 hours is likely true The sample data provide sufficient evidence to reject the null hypothesis that this brand of mosquite repellent is effective for at least 6 hours and thus we conclude that the company s claim that that the mosquito repellent lasts for at least 6 hours is likely false
