The highway police in a certain state are using aerial surveillance to control speeding on a highway with a posted speed limit of 55 miles per hour. Police officers watch cars from helicopters above a straight segment of this highway that has large marks painted on the pavement at 1-mile intervals. After the police officers observe how long a car takes to cover the mile, a computer estimates that cars speed. Assume that the errors of these estimates are normally distributed with a mean of O and a standard deviation of 3.72 miles per hour. a. The state police chief has directed his officers not to issue a speeding citation unless the aerial units estimate of speed is at least 61 miles per hour. What is the probability that a car travelling at 53 miles per hour or slower will be cited for speeding? Round your answer to four decimal places. The probability that a car travelling at 53 miles per hour or slower will be cited for speeding is i b. Suppose the chief does not want his officers…

Deer mice (Peromyscus maniculatus) are small rodents native of North America. Their adult body lengths (excluding tail) are known to vary approximately Normally, with mean μ = 86 mm and standard deviation σ = 8 mm. Deer mice are found in diverse habitats and exhibit different adaptations to their environment. A random sample of 14 deer mice in a rich forest habitat gives an average body length of = 91.1 mm. Assume that the standard deviation σ of all deer mice in this area is also 8 mm. What is the standard deviation of the mean length . (Report in mm and round to 3 decimals) What critical value do you need to use in order to compute a 95% confidence interval for the mean μ Give a 95% confidence interval for the mean body length of all deer mice in the forest habitat. Give a 90% confidence interval for the mean body length of all deer mice in the forest habitat.
Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested.If 4.1% of the thermometers are rejected because they have readings that are too high and another 4.1% are rejected because they have readings that are too low, find the two readings that are cutoff values separating the rejected thermometers from the others.interval of acceptable thermometer readings = _________ °C
Steve, the underpaid graduate student, is interested in determining how many final grades in Dr. Boehring’sclass vary. Steve determines that the standard deviation of final grades in Dr. Tahkstumusch’s class is 7. Steve takes a random sample of 50 final grades from Dr. Boehring’s class and computes a standard deviation of 9.Assume that the final grades in Dr. Boehring’s class are normally distributed. At the 5% significance level, do the data provide sufficient evidence to conclude that the standard deviationσof final grades in Dr. Boehring’sclass are greater than 7? Use the rejection region approach for all of the parts below. (a) Define the appropriate hypotheses (b)State and verify that the proper assumptions hold (c)Use the rejection region approach to perform the test (d) Provide support for your decision regarding the null hypothesis (e) Write a summary of your conclusion in the context of the problem

A single thermometer is randomly selected and tested.If 4.8% of the thermometers are rejected because they have readings that are too high and another 4.8% are rejected because they have readings that are too low, find the two readings that are cutoff values separating the rejected thermometers from the others.interval of acceptable thermometer readings =_____________ °C
A local company makes snack-size bags of potato chips. The company produces batches of 400 snack-size bags using a process designed to fill each bag with an average of 2 ounces of potato chips. However, due to imperfect technology, the actual amount placed in a given bag varies. Assume the population of filling weights is normally distributed with a standard deviation of 0.1 ounce. The company periodically weighs samples of 10 bags to ensure the proper filling process. The last five sample means, in ounces, were 1.99, 2.02, 2.07, 1.96, and 2.01. Is the production process under control? Group of answer choices A. No, because the sample means show a downward trend. B. Yes, because the sample means show a downward trend. C. No, because the sample means fall within the upper and lower control limits. D. Yes, because the sample means fall within the upper and lower control limits.
Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2600 grams and a standard deviation of 600 grams while babies born after a gestation period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 440 grams. If a 35-week gestation period baby weighs 2775 grams and a 40-week gestation period baby weighs 3075 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) A.

A sample of 9 cans of Brand A diet soda gave the mean number of calories of 66.1 per can with a standard deviation of 2.4 calories. Another sample of 16 cans of Brand B diet soda gave the mean number of calories of 68.7 per can with a standard deviation of 4.5 calories. Assume that the calories per can of diet soda are normally distributed for both brands with equal standard deviations. State and test the hypothesis that Brand A has lower mean number of calories per can than Brand B at 5% significance level.
The distribution of heights of a certain breed of terrier has a mean of 71 centimeters and a standard deviation of 9 centimeters, whereas the distribution of heights of a certain breed of poodle has a mean of 29 centimeters with a standard deviation of 5 centimeters. Assuming that the sample means can be measured to any degree of accuracy, find the probability that the sample mean for a random sample of heights of 64 terriers exceeds the sample mean for a random sample of heights of 100 poodles by at most 44.2 centimeters. What is the probability? Round to four decimals. Use standard normal distribution table.
Babies born weighing 2500 grams (about 5.5 pounds) or less are called low-birth-weight babies, and this condition sometimes indicates health problems for the infant. The mean birth weight for children born in a certain country is about 3479 grams (about 7.7 pounds). The mean birth weight for babies born one month early is 2652 grams. Suppose both standard deviations are 460 grams. Also assume that the distribution of birth weights is roughly unimodal and symmetric. Complete parts a through c below. a. Find the standardized score (z-score), relative to all births in the country, for a baby with a birth weight of 2500 grams. (Round to two decimal places as needed.) b. Find the standardized score for a birth weight of 2500 grams for a child born one month early, using 2652 as the mean. (Round to two decimal places as needed.) c. For which group is a birth weight of 2500 grams more common? Explain what that implies. Unusual z-scores are far from 0. Choose the correct answer below. O A. A…
