A researcher wants to test to see if a population mean is different from 6. Based on a sample of size 33 the sample mean is 6.3, and the sample standard deviation is 1.1. Use a 5% significance level to carry out the appropriate hypothesis test.

The critical values of the test statistic that divide the rejection and non-rejection regions are ± what value?

What is the value of the test statistic for the previous problem?   Round your answer to 2 decimal places.

The average cholesterol level in the general US population is 189 mg/dL. A researcher wants to see if the average cholesterol for men in the US is different from 189 mg/dL. She takes a sample of 81 American males and finds a sample mean of 194 mg/dL and a sample standard deviation of 10.4 What is the 90% confidence interval?

To test H0: μ=100 versus H1: μ≠100, a simple random sample size of n=24 is obtained from a population that is known to be normally distributed. A. If x=105.8 and s=9.3 compute the test statistic. B. If the researcher decides to test this hypothesis at the a=0.01 level of significance, determine the critical values. C. Draw a t-distribution that depicts the critical regions. D. Will the researcher reject the null hypothesis? a. The researcher will reject the null hypothesis since...

A medical researcher wants to compare the pulse rates of smokers and non-smokers. He believes that the pulse rate for smokers and non-smokers is different and wants to test this claim at the 0.05 level of significance. A sample of 72 smokers has a mean pulse rate of 75, and a sample of 81 non-smokers has a mean pulse rate of 72. The population standard deviation of the pulse rates is known to be 6 for smokers and 9 for...

Previous studies claimed that the population mean DailyReadTime among subjects is 145 minutes, with a population standard deviation of 25 minutes. Based on the data, conduct a hypothesis test BY HAND (with a 1% significance level) to see if there is evidence that the population mean DailyReadTime is greater than 145 minutes. Sample size is 150. Write down your null and alternative hypotheses. Be sure to use appropriate notation. Calculate the test statistic and give the probability statement for the...

A researcher wants to test H 0 : σ = 1.45 versus H 1 : σ > 1.45 for the standard deviation in a normally distributed population. The researcher selects a simple random sample of 20 individuals from the population and measures their standard deviation as s = 1.57. Find the test statistic: (round to 3 decimal places) χ 0 2 = Find the critical value(s) for a 0.01 significance level: (round to 3 decimal places) χ α 2 =...

We have a left tail one sample test for the population mean. Assume the null hypothesis is true. Use 4% for the significance level. The sample size is 27, the sample mean is 32.8, the sample standard deviation is 4.1, and the null mean is 35. The test result is (a) a correct decision (b) a Type I error (c) a Type II error 3. The test statistic value for the previous problem is

A medical researcher wants to compare the pulse rates of smokers and non-smokers. He believes that the pulse rate for smokers and non-smokers is different and wants to test this claim at the 0.1 level of significance. A sample of 76 smokers has a mean pulse rate of 79, and a sample of 62 non-smokers has a mean pulse rate of 76. The population standard deviation of the pulse rates is known to be 7 for smokers and 8 for...
