A hypothesis test was done on the mean cost of textbooks at UVA in a given semester. the null and alternative hypotheses were H₀: μ=$220 and H₁: μ < 220. A sample of 49 UVA students showed a mean of $212, and a P-value of 0.092 was calculated. The P-value is:

a) The probability of making the wrong decision

b) The probability that the true value is $212

C) The probability that if the true value is $220 we will have a sample mean of $212 or less

d) The probability that if the true value is $220 we will have a sample mean that is equal to $212

e) The probability that the true value is $220

Expert Solution

Ans :

d) The probability that if the true value is $220 we will have a sample mean that is equal to $212

Suppose you want to test the claim that mean cost of textbooks for a stats class (offered by several different universities) is more than $150 at the \alpha ?=.05 significance level. (a) Explain, in the context of the problem, what it would mean to make a type I error. (b) Explain, in the context of the problem, what it would mean to make a type II error. (c) How does the the significance level relate to the type I and/or...

Given the following hypothesis test: “It is believed that the mean amount of water per day that the Gondorans drink is L liters. A random sample of 36 Gondorans is observed. The average amount of water they drink per day is 1.62 liters, with a standard deviation of 0.4 liters. Is the mean amount of water that Gondorans drink less than L liters? Test with α = 0.025.” What is the biggest possible value of L (rounded to two digits...

Use the ”test.vs.grade” data and test the null hypothesis that the mean test score for the population is 70 against the alternative that it is greater than 70. Find a p-value and state your conclusion if α = 0.05. Repeat for the null hypothesis µ = 75. https://www.math.uh.edu/~charles/data/test.vs.grade.csv

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2084 passenger cars in a particular region, 241 had only rear license plates. Among 349 commercial trucks, 53 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....
