Horsepower Cars currently sold in the United States have an average of 135 horsepower, with a standard devi-ation of 40 horsepower. What’s the z-score for a car with 195 horsepower?

A negative z score indicates that an individual's raw score:

A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period. Single Policyholders Married Policyholders ni = 412 n2 = 778 Number making claims = 75 Number making claims = 111 a. Use a= 0.05. Test to determine whether the claim rates differ between single and married male policyholders. z-value (to 2 decimals) p-value (to 4 decimals) We cannot conclude that there is the difference between claim rates. b. Provide a 95% confidence interval (to 4 decimals) for the difference between the proportions for the two populations. Enter negative answer as negative number.

I need to find the test statistic. please round to two decimal places as needed

Answer from D to F   Also, please use the Statistical tables provided

H. : p = 0.65 and H, : p > 0.65 where p= the proportion of students who were quarantined at some point during the Fall Semester of 2020. Identify the correct explanation for a Type Il error. O Conclude the percent was higher than 65%, but it was not higher. Conclude the percent was higher than 65% and it was higher. O Did not conclude the percent was higher than 65%, but it was higher. O Did not conclude the percent was higher than 65% and it was not higher.

Find p-hat and q- hat for the given data, X=280  and  n = 580 Round to three decimals

a certain brand produces box with weight of 100 gr.the average weight of 20 samples equals to 102 gram. distribution of the weight of the boxes is 1.25. Conduct a test about the standart weight of the boxes. does the product still weight 100gram or heigher? Write the z value which you should use for comparison.
