Test the following claim. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s), conclusion aboutthe null hypothesis, and final conclusion that addresses the original claim.Tests of older baseballs showed that when dropped 20 ft onto a concrete surface, they bounced an average of 236.6 cm. In atest of 40 new baseballs, the bounce heights had a mean of 234.5 cm. Assume that the standard deviation of bounce heightsof all new baseballs is 4.5 cm. Use a 0.05 significance level to test the claim that the new baseballs have bounce heights witha mean different from 236.6 cm. Are the new baseballs different?What is the value of the test statistic? (You will need todecide whether to use z-scores or t-scores)z or t= (Round to two decimal places as needed.)Identify the critical value(s) of z or t.z or t=(Round to two decimal places as needed. Use a comma to separate answers as needed.)V Ho. ThereV sufficient evidence to support the claim that the new baseballs are different.

From the provided information, Sample size (n) = 40 The mean of bounce height (x̄) = 234.5 cm…

The students at your school claims that it takes at least 15 minutes to find a parking space. The security performed a study and found that the mean time to find a parking space for randomly selected 25 students were 14.2 with a standard deviation of 3.2. Use a = 0.05 to test student's claim. In this case, the alternate hypothesis is Ο μ > 15 Ομ > 15 Ο μ < 15 Ο μ < 15 μ<

Consider a dataset containing the heights of 38 females who said they prefer to sit in the front of the classroom yields a sample average of 62 inches and a sample standard deviation of 2.5 inches. Suppose that the average height for the general population of college females is 65 inches. An analyst wants to test the claim that the true average height of females who prefer to sit in the front of the classroom is lower than it is for the general population. In the hypothesis for the above claim (at significance level of 10%), the appropriate test, test statistic (name and value), and pvalue is the approximate Z-test with z-statistic = 62 and pvalue = 0. the approximate Z-test with z-statistic = 7.40 and pvalue not calculable because normality is not given. = 0. the approximate Z-test with z-statistic = -7.40 and pvalue = 0.

At a college the scores on the chemistry final exam are approximately normally distributed, with a mean of 73 and a standard deviation of 11. The scores on the calculus final are also approximately normally distributed, with a mean of 78 and a standard deviation of 12. A student scored 79 on the chemistry final and 81 on the calculus final. Relative to the students in each respective class, in which subject did the student do better? a) Calculus b) There is no basis for comparison c) Chemistry d) The student did equally well in each course e) None of the above
In a sample of 80 business trips taken by employees in the HR department, a company finds that the average amount spent for the trips was $1580 with a standard deviation of $350. In a sample of 80 trips taken by the employees in the sales department is $1750 with a standard deviation of $550. When testing the hypothesis that the averageamount spent on trips taken by the salesepartment are higher than those taken by the HR department, if the test statistic is 2.33 and the critical value is 1.96 then what is your conclusion concerning the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesis
A high school counselor asks a college-bound student to complete a Readiness to Leave Home questionnaire. Among high schoolers, the questionnaire has a mean of 38.61 and a standard deviation of 9.05. The student earns a raw score of 21. Type your response to the following questions directly in Moodle: What is the student’s z score? (you do not need to show the calculation) In 1-2 sentences, what does the Z score tell us about the student's readiness to leave home? (show that you know the definition of a Z score & can apply it to this example) How would you recommend that the guidance counselor work with the student? (1 sentence)
