Nonparametric test is a design to counter the non-normal distribution type of data. O True

Assume the samples are random and independent, the populations are nomally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices are classified according to battery type. At a = 0.10, is there enough evidence conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. E Click the icon to view the battery cost data. (a) Let u1. P2. H3 represent the mean prices for the group size 35, 65, and 24/24F respectively. Identify the claim and state Ho and H. H Cost of batteries by type The claim is the V hypothesis.

When Freshman 15 The term "Freshman 15" refers to the claim that college students typically gain 15 lb during their freshman year at college. Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of 2.6 lb and a standard deviation of 10.8 1b (based on Data Set 13 "Freshman 15"). Find the probability that a randomly selected male college student gains 15 lb or more during his freshman year. What does the result suggest about the claim of the "Freshman 15"?

What are the two parameters that determine the shape of normal distribution?   a. Median / Standard deviation   b. Median / Interquartile range   c. Mean / Standard deviation   d. Mode / Variation

What is the difference between the t and z distributions? Which is used more in biological research? Explain your anwser.

The accompanying histogram shows the lengths of hospital stays​ (in days) for all female patients admitted to a certain hospital during one year with a primary diagnosis of acute myocardial infarction​ (heart attack). Complete parts​ (a) through​ (c) below.   ​a) From the​ histogram, determine whether the mean or median is larger. Explain.     A. Because the distribution is nearly symmetric​, the mean is expected to be larger than the median.   B. Because the distribution is nearly symmetric​, the mean is expected to be about the same as the median.   C. Because the distribution is skewed to the high end​, the mean is expected to be larger than the median.   D. Because the distribution is skewed to the high end​, the mean is expected to be smaller than the median.   E. Because the distribution is skewed to the low end​, the mean is expected to be larger than the median.   F. Because the distribution is skewed to the low end​, the mean is expected to be…

Would median and quartiles be the right answer?
