A research center claims that more than \( 25 \% \) of employees in a certain country have changed jobs in the past three years. In a random sample of 260 people from that country, 78 have changed jobs in the past three years At \( \alpha=0.05 \), is there enough evidence to support the center's claim? Complete parts (a) through (d) below. (a) Identify the claim and state \( \mathrm{H}_{0} \) and \( \mathrm{H}_{\mathrm{a}} \). Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. The percentage of employees in the country who have changed jobs in the past three years is not B. More than \( \square \% \) of employees in the country have changed jobs in the past three years. D. At most \( \square \% \) of employees in the country have changed jobs in the past three years. Let p be the population proportion of successes, where a success is the country have changed jobs in the past three years. jobs in the past three years. State \( \mathrm{H}_{0} \) and \( \mathrm{H}_{\mathrm{a}} \). Select the correct choice below and fill in the answer boxes to complete vour choice.

Gallons of milk- \( 24.6,23.84,25.25,21,17.52,19.61,19.83,26.18,34.97 \), \( 29.9,28.59,20.57,26.94,27.24 \) At \( \alpha=0.05 \), test for a significant difference by completing the following. Calculate the value of the test statistic ( 2 decimals). What is the p-value?

When is it appropriate to make inferences about a population based upon data collected from a sample when the sample is selected at random from the population of interest any time an experiment is conducted any time an observational study is conducted when a sample is selected from the population of interest

According to a recent study annual per capita consumption of milk in the United States is 22.6 gallons. Being from the Midwest, you believe milk consumption is higher there and wish to test your hypothesis. A sample of 14 individuals from the Midwestern town of Webster City was selected and then each person's milk consumption was entered into the Microsoft Excel Online file below. Use the data to set up your spreadsheet and test your hypothesis.
