A pharmaceutical company claims that the average dose of the active ingredient of their pain killer medicine is 10 mg. To ensure the quality of their product, the company routinely performs a quality check. The company has established that the upper threshold of the variance is 1.5 mg². in other words, if the UCL of 2 > 1.5 mg2 the company will stop the production of the medicine until the problem is fixed. During the last quality control run the following information was obtained Number of pills evaluated Variance Using a 99% Confidence level: 26 0.48 mg²2 1.

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loeding and unloading and the type of ride, a factorial experiment was designed, Use the folloning data to test for any significant effect due to the loading and unloading method, the type of nde, and interaction.

Mr. Saif has conducted a research study to krow the attitude of graduate students towards entrepreneurship business. In this regard, he has collected the data from the Sultan Oaboos University, Muscat and University of Technology and Applied Sciences, Muscat usinga structured questionnaire. The feedback of 400 students has been collected from these universities. For the data analysIs, the researcher has used exploratory factor analysis and regression to evaluate the factors nfluienaing the attitude of students towards entrepreneurship business. Question: Evaluate the methodology approach used for this study by discussing its features.
Coastal State University is conducting a study regarding the possible relationship between the cumulative grade point average and the annual income of its recent graduates. A random sample of 142 Coastal State graduates from the last five years was selected, and it was found that the sample correlation coefficient between cumulative grade point average and annual income was 0.10. Test for a significant linear relationship between grade point average and annual income for the recent graduates of Coastal State by doing a hypothesis test regarding the population correlation coefficient p. (Assume that the two variables have a bivariate normal distribution.) Use the 0.10 level of significance, and perform a two-tailed test. Then complete the parts below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H. and the alternative hypothesis H₁. Ho :O H₁ :0 (b) Determine the type of test statistic to use.

An examination in biology has been taken by biology majors and also by some students from other majors. It is widely believed that the scores for both groups are normally distributed. A random sample of 27 examinations completed by biology majors and an independent random sample of 16 examinations completed by students from other majors are selected. Among sampled students, the biology majors scored a mean of 536.5 points with a variance of 10,920.25 , and the students from other majors scored a mean of 493.3 points with a variance of 28,493.44 . Can we conclude, at the 0.01 significance level, that the population variance of scores of biology majors, of, is less than o5, the population variance of scores of other majors? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your answers as specified below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative…
Your company is evaluating two cloud-based secured data storage services. "Great Sky," the newer service, claims its uploading and downloading speeds are faster than the older service, "Clear and Steady Skies." You need to make a decision based on published access times for both services at different times and for varying file sizes. To make your decision, you purchase two statistical studies from which you discover the average download time for Great Sky is 0.67 sec. per MB and for Clear Steady Skies is 0.84. Additionally, the studies indicate the following sample information: NGS = 60 ncss = 50, SGS = 0.25 and scss = 0.55. Use a .05, and the five step hypothesis testing procedure to make the appropriate decision. Prepare an Excel worksheet properly labeled and well formatted to share with your boss (a very picky person that truly appreciates good looking work product).
The human resources department of a large investment bank announced that the number of people it interviews monthly has a mean of 105, with a variance of 262.44. The management of the bank suspects that the variance exceeds 262.44. Suppose that the management wants to take a small sample of months and carry out a hypothesis test to see if it's suspicious have support. State the thanks hypothesis Ho and alternative hypothesis H1 that it would use for this test.
I have panel data related to transportation of commodities, where im looking to see the effect on revenue. I included my dummy year variables, and the remaining 3 variables (all continuous). I used Pooled OLS technique and robust SE. i checked for an unobserved affect using the Wooldridge test which was significant indicating serial correlation. I tried to control for the serial correlation by adding a lagged dependent variable into my model, but still had serial correlation. Any suggestions on how i can further remove serial correlation. Should i tried FE or FD?
True or False: Explain Suppose that OLS is unbiased for the following bivariate model: Y = B0 +B1X +u and suppose that the true slope coefficient B1 = 7. If you use the standard t-statistic to test the null hypothesis that the slope coefficient is equal to 0, the probability that you will reject the null hypothesis will increase if you reduce your sample size.
Baseball statisticians studied how often triples (a certain event in a baseball game) occurred in professional games played between 1947 and 2017. A 98 percent confidence interval to estimate the slope of the linear regression line relating the year, x, and the mean number of triples per game, y, yielded (−0.006,−0.002). A check shows that the conditions necessary for inference for the slope of the regression line are met.
In building an arena, steel bars with mean ultimate tensile strength of 400 megapascal(Mpa) with a variance of 81 Mpa were delivered by the manufacturer. The project engineer tested 50 steel bars and found out that the mean ultimate tensile strength is 390 MPa. The decision for the extension of the contract with the manufacturer depends on the engineer. Test the hypotheses whether or not there is no significant difference between the two means using a two-tailed test with a=0.01. 1. What are the appropriate hypotheses for the two-tailed test? 2. What is the test statistics to be used and the reasons for its selection? 3. What is the critical value of c? 4. What is the value of the test statistic or the computed value? 5. Formulate a conclusion about the given situation.
Two groups of mice were injected with a measured amount of tumor pulp. The first group of 27 mice was given a high dosage of chemotherapy while the second group of 30 mice was given a low dosage of chemotherapy. After forty days, the first group had an average tumor size of 0.51cc with a variance of 0.10; the second group had an average tumor size of 0.64cc with a variance of 0.045. Were the tumor sizes of group 1 significantly smaller than those of group 2? What is the observed test statistic?
