For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two-tailed, left-tailed, or right-tailed.The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.2 months. A hypothesis test is to be performed to determinewhether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.2 months.Choose the correct null and alternative hypotheses below.OA. Ho: μ>22.2 monthsHa: μ = 22.2 monthsO D. Ho: H=22.2 monthsHa: μ# 22.2 monthsO E. Ho: μ = 22.2 monthsHa: μ<22.2 monthsWhich of the following is the correct classification of the hypothesis test?A. Two-tailedB. Right-tailedB. Ho: <22.2 monthsHa: μ = 22.2 monthsO C. Left-tailedOC. Ho: H=22.2 monthsHa: μ>22.2 monthsOF. Ho: μ# 22.2 monthsHa: μ = 22.2 monthsNext

You are a manager of a building that hosts the local farmers market for a town. You want to investigate if the average amount of sales for a vendor per week at your building is greater than $2040. After surveying 17 of their vendors, you find that mean sales per week of the vendors sampled was $2110 with a standard deviation of $114.03. What is the value of the test statistic for your hypothesis test? Note: 1- Only round your final answer. Round your final answer to two decimal places.

A graduate student believes that people consider faces with more contrast between lip color and skin tone as more feminine. She identifies the null hypothesis as: Ho: The level of contrast between lip color and skin tone does not affect how feminine a face is considered. She chooses a significance level of 0.05. After she collects the data and computes the sample statistics, it is time for her to make a decision about the null hypothesis. What are the two possible decisions that the graduate student can make? Check all that apply. There is not enough evidence to reject the hypothesis that the contrast between lip color and skin tone affects how feminine a face is considered. There is enough evidence to reject the hypothesis that the contrast between lip color and skin tone does not affect how feminine a face is considered. There is enough evidence to reject the hypothesis that the contrast between lip color and skin tone affects how feminine a face is considered. ☐ There is not enough…

Using the Hypothesis Testing Procedures, please complete: The mean age of senators in the 109th Congress was 60.35 years old. A random sample of 40 senators from various state senates had an average age of 55.4 years, and the population standard deviation is 6.5 years. At a = 0.05, is there sufficient evidence that state senators are on average younger than the Senators in Washington
