Playing 10 rounds of golf on his home course, a golf professional averaged 71.3 with a standard deviation of 2.64. (a) (10 points) Test the null hypothesis that the consistency of his game on his home course is actually measured by σ = 2.40, against the alternative hypothesis that he is less consistent. Use the level of significance 0.05. Assume that the distribution of his score, although discrete, is approximately normal. (b) (5 points) If the distribution of his scores has a long right-hand tail, are your calculations in part (a) valid? Explain.

A standardized exam's scores are normally distributed. In a recent year, the mean test score was 21.1 and the standard deviation was 5.7. The test scores of four students selected at random are 14, 22, 7, and 35. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 14 is (Round to two decimal places as needed.) The z-score for 22 is (Round to two decimal places as needed.) The z-score for 7 is (Round to two decimal places as needed.) The z-score for 35 is (Round to two decimal places as needed.) Which values, if any, are unusual? Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. The unusual value(s) is/are (Use a comma to separate answers as needed.) O B. None of the values are unusual.
From generation to generation, the mean age when smokers first start to smoke varies. However, the standard deviation of that age remains constant at around 2.1 years. A survey of 42 smokers of this generation was done to see if the mean starting age is at least 19. The sample mean was 18.1 with a sample standard deviation of 1.3. Do the data support the claim at the 5% level?Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) State the distribution to use for the test. (Round your answers to four decimal places.) X ~ , What is the test statistic?

In Company X, the personnel department gives two aptitude tests to applicants. One measures verbal ability while the other measures quantitative ability. From many years of experience, the company has found that a person's verbal score Y1 is normally distributed with mean of 50 and standard deviation (stdev) of 10. The quantitative scores Y2 are also normally distributed with mean of 100 and stdev 20. Y1 and Y2 appear to be independent. A composite score, Y, is assigned to each applicant where: Y= 3Y1 + 2Y2.Applicants whose composite scores are below 375 are automatically rejected. What is the probability that a random applicant gets automatically rejected? If six applicants submit resumes, what are the chances that fewer than half will fail the screening test?
The weights of an adult female population of killer whales are approximately normally distributed with a mean of 18,000 pounds and a standard deviation of 4,000 pounds. The weights of an adult male population of killer whales are approximately normally distributed with a mean of 30,000 pounds and a standard deviation of 6,000 pounds. A certain adult male killer whale weighs 24,000 pounds. This adult male would have the same z-score weight as a female killer whale whose weight, in kilograms, is equal to which of the following? Select one: 1. 24,000 2. 30,000 3. 36,000 4. 21,000 5. 14,000

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1479 and a standard deviation of 310. The local college includes a minimum score of 642 in its admission requirements.What percentage of students from this school earn scores that fail to satisfy the admission requirement?P(X < 642) = %

A random sample of 100 drug dealers had a mean Wanting Recognition (WR) score of 39 points, with a standard deviation of 6 points. Recall that the WR score is a quantitative measure of a person’s level of need for approval and sensitivity to social situations. (Higher scores indicate a greater need for approval.) A criminal psychologist claims that the range of WR scores for the population of convicted drug dealers is 42 points. Do you believe the psychologist’s claim? (Hint: Assume the population of WR scores is normally distributed.)
In a simulation project, the time (in minutes) between arrivals of customers to a post office is to be modelled. The team collected the arrival data of 200 customers and arranged it to perform a x² goodness- of-fit test in the table below. They checked the histogram of the data and thought that the distribution should be Normal with the estimated mean value T = 124 min and standard deviation s = 15.50 min.

The owner of a dry cleaning store belleves that the mean amount a customer spends on a dry cleaning order exceeds $22.09. A statistician has said to him that he can be statistically sure that his bellef is true if the mean amount of 100 randomly chosen customer bills is greater than $23.25, or X> 23.25, It is assumed that the standard deviation in the bill amounts is $12.19 (a= 12.19).
