A random sample of
777
subjects was asked to identify the day of the week that is best for quality family time. Consider the claim that the days of the week are selected with a uniform distribution so that all days have the same chance of being selected. The table below shows goodness-of-fit test results from the claim and data from the study. Test that claim using either the critical value method or the P-value method with an assumed significance level of
alphaαequals=0.05

At least one day of the week has a different chance of being selected.
All days of the week have a different chance of being selected.
At least two days of the week have a different frequency of being selected.
All days of the week have an equal chance of being selected.

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A coin mint has a specification that a particular coin has a mean weight of 2.52.5 g. A sample of 3737 coins was collected.

The table below shows the frequencies for the days of the weeks that prospective mothers were admitted to a hospital to give birth. A physician claims that because many births are induced or involve cesarean section, they are scheduled for days other than Saturday or Sunday, so births do not occur on the seven different days of the week with equal frequency. Use a 0.010.01 significance level to test that claim. Day nbspDay Sun Mon Tues Wed Thurs Fri Sat...

A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2720 occupants not wearing seat belts, 30 were killed. Among 7791 occupants wearing seat belts, 18 were killed. Use a 0.01 significance level to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) through (c) below. Test the claim using a hypothesis test. Consider the first sample to be the sample of occupants not wearing seat belts and the second sample...
