Professor Jennings claims that only 35% of the students at Flora
College work while attending school. Dean Renata thinks that the
professor has underestimated the number of students with part-time
or full-time jobs. A random sample of 85 students shows that 38
have jobs. Do the data indicate that more than 35% of the students
have jobs? Use a 5% level of significance.

A report claims that 46% of full-time college students are
employed while attending college. A recent survey of 60 full-time
students at a state university found that 28 were employed. Use
the five-step p-value approach to hypothesis testing and a 0.05
level of significance to determine whether the proportion of
full-time students at this state university is different from the
national norm of 0.46. find the t statistic find the p value find
the critical value

A survey was conducted at a college to determine the number of
hours students spent outside on weekends during the winter. For
students from cold weather climates, the results were M =
8, SD = 1.5. For students from warm-weather climates, the
results were M = 5, SD = 4.2. Explain what these
numbers mean to a person who has never had a course in statistics,
and suggest conclusions the person can draw from these results.
These conclusions use the...
