A study was conducted to compare the length of time between men and women to assemblea certain product. Sample standard deviation in a random sample of times for 11 men was8.6 minutes, and sample standard deviation in a random sample of times for 13 women was6.9 minutes. Past experience indicate that population of times is normal for both men andwomen.Is it sufficient sample evidence to conclude that the variance of the lengths of time for menis larger than the variance of the lengths of time for women?Test appropriate hypothesis at a = 0.05 level of significance using critical value approach.Use S²/S2 as test statistic.Construct a 90% confidence interval for the ratio of two population variances.a. State null and research hypothesesH:H₁b. The observed value of test statistic isc. State the rejection regiond. Insert the word sufficient or insufficient into the following statement.There isof time for men is larger than the variance of the lengths of time for women._sample evidence to conclude that the variance of the lengthse.

The mean annual temperature of a place is reported in literature to be 16.5°C. Measurements over 1992 to 2009 show a mean temperature of 14.65°C and a variance of 4.75°C. Test the hypothesis that the mean annual temperature of the place has changed from the past at a significance level of 5%.
Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.6 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 1313 samples is 7.2 ppm with a variance of 0.49 Assume the population is normally distributed. A level of significance of 0.02 will be used. Make the decision to reject or fail to reject the null hypothesis.

The mean fineness of yarn is expected to be greater than the standard value of 5 units. To test this claims, the factory graded 16 specimens of the yarn and found the sample mean to be 5.9 units. Assume that the measurement of fineness is normally distributed with a variance of 4.0. We can state (exactly one option is correct) The p-value is 0.1632 and there is strong evidence that the mean exceeds by 5 units at 17% level of significance. The p-value is 0.0002 and there is strong evidence that the mean exceeds 5 units at 1% level of significance. The p-value is 0.3264 which indicates the data are consistent with a mean of 5 units at 35% level of significance.

A researcher decides to measure anxiety in group of bullies and a group of bystanders using a 23-item, 3 point anxiety scale. Assume scores on the anxiety scales are normally distributed and the variance among the group of bullies and bystanders are the same. A group of 30 bullies scores an average of 21.5 with a sample standard deviation of 10 on the anxiety scale. A group of 27 bystanders scored an average of 25.8 with a sample standard deviation of 8 on the anxiety scale. You do not have any presupposed assumptions whether bullies or bystanders will be more anxious so you formulate the null and alternative hypothesis based on that.

2. The average zone of inhibition (in mm) for mouthwash L as tested by the medical technology students has been known to be 9mm. A random sample of 10 mouthwash L was tested and the test yielded an average zone of inhibition of 7.5mm with a variance of 25 mm. Is there enough reason to believe that the anti-bacterial property of the mouthwash has decreased? Test the hypothesis that the average zone of inhibition of the mouthwash is no less than 9mm using 0.05 level of significance. A. State the hypotheses. B. Determine the test statistic to use. C. Determine the level of significance, critical value, and the decision rule. D. Compute the value of the test statistic. E. Make a decision. F. Draw a conclusion.
