thank you for helping me, ive been having a very hard time. i appreciate you!! 1 2 3 (1 point) For each situation, state the null and alternative hypotheses: (Type "mu" for the symbolu, e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1. Please do not include units such as 'mm' or '$ in your answer.)...

Test the following claim. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim. A manual states that in order to be a hit, a song must be no longer than three minutes and thirty seconds (or 210 seconds). A simple random sample of 50 current hit songs results in a mean length of 252.5 sec. Assume the population standard deviation of song lengths is 53.5 sec....
9. (14 points) For each scenario below, indicate the appropriate test and alternative hypothesis by selecting two let- ters from the following: (A) single mean, (B) difference of means, (C) paired means, (D) correlation, (E) single proportion, (F) difference of proportions. (G) chi-square independence, (X)H: < or H : > Bo, (Y) H :8 , and (Z) H, the 2 nominal variables are not independent. Here, stands for a population parameter and its assumed value under the null hypothesis. Each...
(a) Find 6,-x2). answer: (b) Determine the rejection region for the test of H. : (H1 - H2) = 2.1 and H,:(H1 - H2) > 2.1 Use a = 0.01. Z > (c) Compute the test statistic. z = The final conclustion is A. We can reject the null hypothesis that (H1-H2) = 2.1 and accept that (H1-H2) > 2.1. OB. There is not sufficient evidence to reject the null hypothesis that (M - M2) = 2.1. (d) Construct a...
