State your decision to the significance test in terms of the null hypothesis. According to a recent poll, the percentage of Americans who would vote for the incumbent president is 53%. If a random sample of 100 people in New York results in 45% who would vote for the incumbent, test the claim that the percentage of people in New York who would vote for the incumbent president is different from 53%. Use the following results and a 0.10 significance...

Identify the null hypothesis. alternative hypothesis, test statistic, decision about the null hypothesis and final conclusion that addresses the original claim Various temperature measurements are recorded at different times for a particular city. The mean of 20 degrees is obtained for 60 temperatures on 60 different days. Assuming that the population standard deviation is 1.5 degrees, test the claim that the population mean is 22 degrees. Use a 0.05 significance level Hou = 22; H1 is u# 22 Test statistic:...

Post an example of a scenario that would warrant either a one-sample or a two-sample test. This can be a hypothetical example. Please state H0 and H1 and explain why your hypothetical example qualifies as either a one- or two-sample test. (Please recognize that one- and two-sample tests are not the same as one- or two-tail tests.) Also, clearly state the reason(s) this hypothesis test would be conducted. You do not actually have to complete the hypothesis test steps.

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 2142 passenger cars in a particular region, 249 had only rear license plates. Among 332 commercial trucks, 49 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....

A random sample is taken from a normal population. Do the hypothesis test to determine if there is evidence that the population standard deviation is greater than 5. Use a level of significance of α = 0.05. n = 25 xbar = 68.7 s = 6.2 Use the appropriate notation to show the hypotheses. H0: H1: The critical value is _________ = _______________________ The test statistic is __________= ________________________ The p value is __________________________________

In a one-tailed t-test, the null hypothesis is H0: population β1≥0. If the test statistic = – 1.529, and the critical value you find from the t-table is 2.164, do you reject the null hypothesis?

Determine a hypothesis that the following data may address and perform a Chi-square test Goodness of Fit test on following data.

How do you solve for the P-value?
In a hypothesis test with hypotheses Ho : j < 54 and H1 :u > 54, a random sample of 24 elements selected from the population produced a mean of 59.0 and a standard deviation of 14.0. The test is to be made at the 2.5% significance level. Assume the population is normally distributed. What is the critical value of t? 1.96 02.064 • 2.069 -2.069 What is the value of the test...
