A dean in the business school claims that GMAT scores of applicants to the school's MBA program haveincreased during the past 5 years. Five years ago, the mean and standard deviation of GMAT scores of MBAapplicants were 550 and 60, respectively. 30 applications for this year's program were randomly selected and theGMAT scores recorded. If we assume that the distribution of GMAT scores of this year's applicants is the same asthat of 5 years ago, find the probability of erroneously concluding that there is not enough evidence to supports theclaim when, in fact, the true mean GMAT score is 590. Assume a is 0.02.P(Type II Error) =

Solution To calculate probability we will use z distribution.

It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 13 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 13 respondents was 42 hours, with a standard deviation of 8 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean u. Can we conclude that u is greater than 40 hours? Use the 0.05 level of significance. 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 in the table. (If necessary, consult a list of formulas.)

The Richard family has twins Ron and Rebecca. Both Ron and Rebecca graduated from college 2 years ago, and each is now earning $60,000 per year. Ron is an engineer the mean salary for engineers with less than 5 years' experience is $70,000 with a standard deviation of $5,000. Rebecca works in the retail industry, where the mean salary for executives with less than 5 year's experience is $40,000 with a standard deviation of $11,000. What is the z score for Ron?
Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. Lucille's class had an average grade of 85 and the standard deviation was 3. Lucille earned 89.5 on the exam. Rocio's class had an average grade of 83 and the standard deviation was 4. Rocio earned 87.4 on the exam. Cristina's class had an average grade of 76 and the standard deviation was 6. Cristina earned 79.3 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam.

The blue catfish (Ictalurus Furcatus) is the largest species of North Amercian catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to Amercian Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds.a) If you going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses?H0H0: H1H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed

It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 15 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 15 respondents was 43 hours, with a standard deviation of 8 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean μ. Can we conclude that μ is greater than 40 hours? Use the 0.05 level of significance. State the null hypothesis H0 and the alternative hypothesis H1 Find the t-test df & Solve the t-test value Find the critical value Can we conclude, at the 0.05 level of significance, that the mean number of hours worked per week by college graduates is greater than 40 hours? Yes or No?
Forty refrigerators from two different models of a refrigerator manufacturer are compared to see if the smaller model uses less energy than the larger model. The energy was measured in kilowatt hours per month (kwh/mo). From years of testing these models, it is known that the standard deviation of kwh/mo is 34 kwh/mo for the smaller model and 40 kwh/mo for the larger one. From this survey, the sample means and standard deviations are 125 and 34, and 90 and 40, respectively. If we conduct a hypothesis test, the p-value is Group of answer choices 0.0000 0.0010 0.0004 0.0002

Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50; ¯x=40.72 pounds; s=5.03pounds Calculate your test statistic.
