Mr. Gomez is a quality control officer in a candy company. One of his responsibilitiesis ensuring that candy bars follow the standard weight. The average weight of candybars should deviate no more than 20 grams from the printed weight of 350 grams. Mr.Gomez gets a sample of 40 bars from each packing machine everyday and weighsthem. Today's sample from Machine A yielded a mean of 338 grams and a standarddeviation of 10 grams. Is there evidence that Machine A performs within standards fortoday?What is the lower limit of the confidence interval?

The average triglyceride level of adult males is 126 milligrams per deciliter. You want to determine whether the true mean male triglyceride level is more than the average. You decide to pull a random sample of eight adult males and measure their triglyceride level. You find the sample mean is 127.9 milligrams per deciliter and the standard deviation is 4.12 milligrams per deciliter. What are the test statistic and the p-value? O The test statistic is 1.9 and the p-value is 0.1174. O The test statistic is 0.1174 and the p-value is 1.9. O The test statistic is 1.46 and the p-value is 1.30. O The test statistic is 0.1174 and the p-value is 1.30. O The test statistic is 1.30 and the p-value is 0.1167.
According to records kept by Mariposa County, the average (mean) amount of time that it takes for employees to be reimbursed for professional expenses incurred in service to the county is 36 days, with a standard deviation of 5 days. The distribution is normal. The head of the Mariposa County Accounting Department wants to establish a standard regarding the length of time that employees can expect to wait to receive reimbursement for professional expenses. She wants to publish a standard that states the number of days it takes the department to process 98% of the claims filed. Help the department head find that standard.
The speed of cars driving past Johnson City High School, on 666 Reynolds Rd, were recorded over one school year. The speed limit on that part of Reynolds Rd is 20 mph. The mean of the speed readings was 24.19 mph, with a standard deviation of 3.56 mph.
The average amount of rainfall in Puerto Rico last month was 3.5 inches, according to the National Meteorology Center. Suppose that a normal distribution can be used and that the standard deviation is 0.8 inches. a. What percentage of the time was last month's rainfall greater than 4 inches? (3 points)b. What percentage of the time was rainfall less than 3 inches? (3 points)c. A month is considered extremely humid if the rainfall is 10% higher for that month. How much rainfall must be in April to be considered an extremely humid month? (3 points)
In 2005, the federal aviation administration updtaed its passengers weight standards to an average of 190 pounds in the summer (195 in the winter). This includes clothing and carry- on baggage. The FAA, however did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are normally distributed especially when the population includes both men and women, but they are not very non- normal. A computer plane carries 25 passangers. What is the apporximate probability that, in the summer, the total weight of the passengers exceeds 5200 pounds?
The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.05 level that the drug stays in the system for more than 352 minutes. For a sample of 54 patients the mean time the drug stayed in the system was 360 minutes. Assume the population standard deviation is 25. Find the p-value of the test statistic
Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 42 randomly selected people who train in groups and finds that they run a mean of 47.1 miles per week. Assume that the population standard deviation for group runners is known to be 4.4 miles per week. She also interviews a random sample of 47 people who train on their own and finds that they run a mean of 48.5 miles per week. Assume that the population standard deviation for people who run by themselves is 1.8 miles per week. Test the claim at the 0.01 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
The chocolate chip cookies that are produced at Perry’s Cookie Emporium have weights which are approximately normally distributed with the mean weight 180 grams and with standard deviations 20 grams. The cookies, however, are sold by count, not by weight. Perry wants to improve his image, so he decides to set aside lightest 20% of the cookies to be packaged and sold separately. What cookie weight will divide the lightest 20% from the heaviest 80%?
A manufacturer of bolts has a quality control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality control engineer knows that the bolts coming off the assembly line have a mean length of 8cm with a standard deviation of 0.05 cm. For what length will a bolt be destroyed?
When we make a set of measurements, the width or standard deviation of the sampled parent distribution generally reflects the accuracy of our measurement methods. True or False
During 2003 gasoline prices reached record high prices in 16 states United States (The Wall Street Journal, March 7, 2003). Two of the states affected were California and Florida. The American Automobile Association foundas sample mean price per gallon $2.04 in California and $1.72 per gallon in Florida. Use 40 as the sample size for California and 35 as the sample size for Florida. Suppose that previous studies indicate that the population standard deviation in California it is 0.10 and in Florida 0.08.a) Test at the 10% level the null hypothesis that the population means of the gasoline prices are equal against the alternative hypothesis that, on average, Gasoline is more expensive in California than in Florida.b) Find the p-value of this test.
The combined SAT scores for the students at a local high school are normally distributed with a mean of 1469 and a standard deviation of 296. The local college includes a minimum score of 1824 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?
