6. b. Test statistic = ?c. P-value = ? d. Reject/Accept null hypothesis ? -0.92 is wrong for the test statistic Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medicalresearch using stem cells obtained from human embryos." Of those polled, 484 were in favor, 397 were opposed, and 116 were unsure. Apolitician claims that people don't really understand the stem cell issue and their responses to such questions are random responsesequivalent to a coin toss. Exclude the 116 subjects who said that they were unsure, and use a 0.01 significance level to test the claim thatthe proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim?

Find the P-values while (hypothesis) testing mean.The principal of a school wants to test the average IQ of students at her school. She administers an IQ test to 36 randomly selected students. Among the sampled students, the sample average IQ is 108.a) What is the P-value when testing the hypothesis that the average IQ is at least 110? Assume that population standard deviation is known to be 10.P-value = (round to 4 decimals)b) What is the P-value when testing the hypothesis that the average IQ is at most 110? Assume that the sample standard deviation is known to be 10.P-value = (round to 4 decimals)c) What is the P-value when testing the hypothesis that the average IQ is not 110? Assume that population standard deviation is known to be 10.P-value = (round to 4 decimals)
1) If your p-value is less than a significance level , then your decision is to fail to reject the null hypothesis. True or False 2)The test statistic, z, in a hypothesis test measures the difference between the sample proportion and the hypothesized proportion in terms of standard deviations. True or False

Suppose that the batting average for all major league baseball players after each teamcompletes 100 games through the season is 0.248 and the standard deviation is 0.034. Thenull hypothesis is that American League infielders average the same as all other majorleague players. A sample of 46 players taken from the American League reveals a meanbatting average of 0.255. What is the value of the test statistic?
I need help finding the test statistic, p value, whether to reject or fail to reject and do the results support the belief in the problem. Thanks in advance for your help
Suppose the number of observations in a sample is 30, sample mean is 73 and sample standard deviation is 13. Perform a test of null hypothesis is `population mean is equal to 72` and the alternative hypothesis is `population mean is greater than 72`. (Use 5% significance level) a) 0.42: accept the null b) -0.42: reject the null c) 0.25: accept the null d) -0.25: reject the null
Average heart rate for Americans is 72 beats/minute. A group of 25 individuals participated in an aerobics fitness program to lower their heart rate. After six months the group was evaluated to identify is the program had significantly slowed their heart. The mean heart rate for the group was 69 beats/minute with a standard deviation of 6.5. Was the aerobics program effective in lowering heart rate? a) What would be the null hypothesis and alternative hypothesis in this study? b) What is your tcrit(t critical value) ? c) Is there a significant difference between the two groups? d) Interpret your answer. e) Write out your t-value in APA format. *ANSWER ALL PARTS OF THE QUESTION*
We want to know if there is a difference between the mean list price of a three bedroom home, μ3, and the mean list price of a four bedroom home, μ4, H0:μ3=μ4 versus Ha:μ3≠μ4. Suppose we get a p-value of 0.1325, which is the proper conclusion of this test? a) We accept the null hypothesis at 5% significance. There is extremely strong evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. b) We reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. c) We fail to reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. d) We reject the null hypothesis at 5% significance.

Hello!! Can you pls help me answer this problem? Thank you!!
A sample of 36 students is found to have a mean score on GMAT Math test was (A + 500). The standard deviation is A scores. The same supervisor in the last example like to see if a student 5. scored significantly below the population mean score on the GMAT Math test 515. Is there sufficient evidence to support the claim at 10% level of significance? Note that: A is first two-digit number (before English alphabet letter) from your college ID. B is last four-digit number (after English alphabet letter) from your college ID. For example, if your MEC ID is 16F23451, then A = 16 and B = 3451
The manager of a driving school claims that the mean time taken to learn how to drive a car is 8 hours for all new drivers. A sample of 16 new drivers showed that the mean time taken by them to learn how to drive a car is 9.5 hours with a standard deviation of 1.5 hours. Test at the 1% significance level if the mean time taken to learn how to drive a car by all new drivers is greater than 8 hours.
