A study was conducted to examine how anxiety (measured on a metric scale) varies for people from different age groups (<18 years, 19 - 29 years, 30 - 39 years, 40+ years). It was hypothesised that people <18 years old would have the least anxiety of the four age groups. It was also hypothesised that people 40+ years old would have more anxiety than people 19-29 years old. Which of the following would be an appropriate statistical test to conduct, which addresses these hypotheses?

In a study of 110 women and 116 men, it was found that mean body temperature for women was 97.690 F and mean body temperature for men was 97.450 F. Assume that the populations are independent, and the standard deviations were found to to be 0.89o F for women, and 0.660 F for men. Use an α = 0.05 significance level to test the claim that woman and men have different mean body temperatures. For full credit your hypothesis test must include: the claim, the null and alternate hypothesis, your test statistic and corresponding p-value, your decision, and the interpretation of your decision as it relates to the claim. It is acceptable to use technology to calculate the test statistic and the p-value here.
