A random sample of 25 college males was obtained and each was asked to report their actual height and what they wished as their ideal height. A 95% confidence interval for _µ_d = average difference between their ideal and actual heights was 0.8" to 2.2". Based on this interval, which one of the null hypotheses below (versus a two-sided alternative) can be rejected? Select one: a. H0: µd = 2.0 b. H0: µd = 1.0 c. H0: µd = 1.5 d. H0: µd = 0.5

You measure 29 dogs' weights, and find they have a mean weight of 55 ounces. Assume the population standard deviation is 2.9 ounces. Based on this, what is the maximal margin of error associated with a 95% confidence interval for the true population mean dog weight.Give your answer as a decimal, to two places±±  ounces

A researcher wants to estimate the mean blood cholesterol level of young men ages 15-25 with a 93.66% confidence interval. The blood cholesterol level of young men follows a Normal distribution with standard deviation σσ = 35 mg/dl. How large a sample would the researcher need to take to estimate the mean blood cholesterol to within 11 mg/dl?

The mean number of eggs per person eaten in the United States is 263. Do college students eat less eggs than the average American? The 62 college students surveyed averaged 260 eggs per person and their standard deviation was 30.3. What can be concluded at the  αα = 0.05 level of significance? For this study, we should use     The null and alternative hypotheses would be:       H0:H0:            Correct           H1:H1:            Correct       The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is     αα Based on this, we should      the null hypothesis. Thus, the final conclusion is that ... The data suggest that the sample mean is not significantly less than 263 at αα = 0.05, so there is statistically insignificant evidence to conclude that the sample mean number of eggs consumed by college students per year is less than 260. The data suggest that the population mean is not…
