Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject Ho for the given level of significance a. Two-tailed test with test statistic z = - 1.96 and a = 0.1 P-value = (Round to four decimal places as needed.) State your conclusion. Fail to reject Ho Reject Ho

A sample mean, sample size, and population standard deviation are provided below.  Use the one-mean z test to perform the required hypothesis test at the 10% signifigance level.  Find the test statistics and P-Values. x bar-22 n=36 s=5 Ho: mean =24 Ha: mean < 24

A sample​ mean, sample​ size, and sample standard deviation are provided below. Use the​ one-mean t-test to perform the required hypothesis test at the 10​% significance level.   x=25​, s=10​, n=24​, H0​: μ=24​, Ha​: μ>24   The test statistic is t= (round to two decimals as needed)

Help with Q2

find test statistic and p value.  if you can explain how to do it in Stat crunch; extra points. im frustrated.

An electrician wants to know whether batteries made by two manufacturers have significantly different voltages. The voltage of 131 batteries from each manufacturer were measured. The population standard deviations of the voltage for each manufacturer are known. The results are summarized in the following table. Manufacturer Sample mean voltage (millivolts) Population standard deviat A 116 3 115 4 What type of hypothesis test should be performed? Right-tailed z-test v What is the test statistic? Ex: 0.12 Does sufficient evidence exist to support the claim that the voltage of the batteries made by the two manufacturers is different at the a = 0.01 significance level? Select v

Please help me with this question.

Test the claim about the population mean, u, at the given level of significance using the given sample statistics. Claim: u= 40; a = 0.06; o = 3.41. Sample statistics: x = 39.9, n = 71 Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: H>40 О В. Но: н- 40 Hai H= 40 Ha: H 40 Ο F. Ho: μ# 40 Ha:H= 40

following hypothesis test for matched data: Но : ld H1 : Hd + 0 For a sample of 18, it was found that d = 2.9 and sa = 3.56. Determine each of the following: The value of the test statistic: For a = 0.025, the final conclusion is O A. There is enough evidence to say that Hd = 0 B. There is enough evidence to say that ud # 0 C. There is not enough evidence to say that ld = 0 D. There is not enough evidence to say that Hd + 0.
