Exam data were collected from a representative sample of 37 students. Their mean score was 90.27 points with a standard deviation of 6.793 points. StatKey was used to construct a bootstrap sampling distribution, which was approximately normal with a standard error of 1.121. Construct a 95% confidence interval to estimate the mean score in the population of all students using the standard error method.

Research question: Are more than half of all Italian adults lactose intolerant?  H0: p = 0.50Ha: p > 0.50 Data were collected from a representative sample of 50 Italian adults. Each took a lactose intolerance test. In the sample, 36 were classified as lactose intolerant.  StatKey was used to conduct a randomization test. The result was a 0.0014 p value. Use this information to choose the correct answers below.   We should [decision] the null hypothesis because the p-value is [alpha] the 0.05 alpha-level. Thus, [conclusion] sufficient evidence that more than half of all Italian adults are lactose intolerant.
