It is commonly believed that the mean body temperature of a healthy adult is 98.6° F. You are not entirely convinced. You believe that it is higher than 98.6° F. The temperatures for 12 randomly selected healthy adults are shown below. Assume that the distribution of the population is normal. 100.1, 96.8, 98.7, 100, 99.1, 98.3, 97.5, 100.9, 99.1, 100, 98.1, 100.1 What can be concluded at the a = 0.05 level of significance? a.

A survey of 30 people was conducted about how many siblings they had. A graph was created that showed the percentage of the survey group, which had each number of siblings. The "frequency" column in the table shows the number of responses that having a certain number of siblings received. Using appropriate and precise statistical terminology, describe the distribution and provide an explanation for the distribution being a certain way.
