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...

In order to conduct a hypothesis test for the population mean, a random sample of 24 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 4.8 and 0.8, respectively.(You may find it useful to reference the appropriate table: z table or t table) Hot μ 4.5 against HA: μ > 4.5 a-1.

(1) To test Ho: p=0.3; H :p > 0.3, a simple random sample of size n=200 is obtained from a population such that n < 0.05N. (a) If x = 75 and n=200, compute the test statistic zo. (b) Test the hypothesis using (i) the classical approach and (ii) the P-value approach. Assume an a= 0.05 level of significance. (c) What is the conclusion of the hypothesis test?

You conduct a hypothesis test about a population proportion p at a significance level of a = .01 using a random sample of size n = 38. Your test statistic follows a standard normal distribution when the null hypothesis is true as an equality, and its value obtained from the sample is z = -2.75. Use the Distributions tool to help you answer the questions that follow. Select a Distribution Distributions 0 1 2 3 If you perform a lower...
