Consider a scenario where you have two samples. Sample 1 contains 50 observations, has the sample average value of 38 and the sample standard deviation of 2.5. Sample 2 contains 50 observations, has the sample average of 39 and the sample standard deviation of 2.0.

Based on this information, please conduct a 95% significance test for the equality of the two population means. Note that we don’t know the population standard deviations but we CAN assume that they are equal.

Question 2 options:

The test fails to reject the null that the two population means are equal

The test rejects the null that the two population means are equal

None of the above

We collect two samples. Sample one has the average value of 75 and contains 30 observations. Sample two has the average value of 80 and has 50 observations. The population standard deviation associated with the first sample is known to be 10 and the population standard deviation associated with the second sample is known to be 12. Based on the above information would a 90% test (alpha is 10%), reject or fail to reject the hypothesis that the mean of...

Assume that we collect a sample of 30 observations and compute the following sample statistics: the sample average = 55; the sample standard deviation =15. Please conduct a test with alpha equal to 10% and the null hypothesis that the population mean is 60. What is the conclusion of this test? a) the test rejects the null hypothesis b) the test fails to reject the null hypothesis c) not enough information is provided to conduct the test

Consider a scenario in which we decide to compare the price of our textbook on eBay versus in the University bookstore. For that purpose, we collect 8 observations of sold used copies of the book on eBay. The average price on eBay is $60. We also compute the sample standard deviation of $20. The price at the University bookstore is $75 for a used copy. Please construct a 95% significance test for the hypothesis that the average price of the...

Two random samples are selected from two independent populations. A summary of the samples sizes, sample means, and sample standard deviations is given below: n1=39,n2=40,x¯1=50.3,x¯2=73.8,s1=6s2=6.1 Find a 98% confidence interval for the difference μ1−μ2 of the population means, assuming equal population variances.

A random sample of 121 observations from a population with standard deviation 50 yielded a sample mean of 120. (a.)Test the null hypothesis that μ= 110 against the alternative hypothesis that μ >110, using α=.05 Interpret the results of the test. (b.)Test the null hypothesis thatμ= 110 against the alternative hypothesis thatμ6= 110, using α=.05 Interpret the results of the test. (c.)compare the p−values of the two tests you conducted. Explain why the results differ.

17. A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled and the average error from the industry standard is measured in millimeters. The results are shown below. Process A Process B Sample mean 2.0 3.0 Standard deviation 1.0 0.5 Sample size 12 14 The researcher is interested in determining whether...

A sample of 36 observations is selected from a normal population. The sample mean is 49, the population standard deviation is 5. Conducting the following test of hypothesis using the 0.05 significance level, we want to know whether the population mean is no different from 50. Is this a one-tailed test or two tailed test ?

For a random sample of 50 measurements of the breaking strength of Brand A cotton threads, sample mean ¯x1 = 210 grams, sample standard deviation s1 = 8 grams. For Brand B, from a random sample of 50, sample mean ¯x2 = 200 grams and sample standard deviation s2 = 25 grams. Assume that population distributions are approximately normal with unequal variances.
