A tire company claims that the lifetimes of its tires average 50500 miles. The standard deviation of tire lifetimes is known to be 5500 miles. You sample 150 tires and will test the hypothesis that the mean tire lifetime is at least 50500 miles against the alternative that it is less. Assume, in fact, that the true mean lifetime is 50000 miles. You are given the opportunity to sample more tires. How many tires should be sampled in total so...

Suppose that a category of world class runners are known to run a marathon (26 miles) in an average of 146 minutes with a standard deviation of 14 minutes. Consider 49 of the races. Let X = the average of the 49 races. I. Give the distribution of X-bar. (Round your standard deviation to two decimal places.) X-bar ~ ____ ( ____ , ____ ). II. Find the probability that the runner will average between 143 and 148 minutes in...

A company claims that the average lifespan of a bicycle tire that they manufacture is 1200 miles. You randomly and independently collect a sample of 31 of these tires and find that the average distance these tires lasted was 1125.7 miles, with a standard deviation of 275 miles. A 90% confidence interval for the population mean lifetime of these tires is (1041.9, 1209.5). Select all true statements. Group of answer choices The confidence interval indicates that the company's claim that...

In 1940 the average size of a U.S. farm was 174 acres. Let's say that the standard deviation was 59 acres. Suppose we randomly survey 39 farmers from 1940. I.   In words, define the random variable X. II. In words, define the random variable X-bar? III. Give the distribution of X-bar. (Round your standard deviation to 2 decimal places) X ~ ____ ( ____, ____ ). IV. The middle 50% of the distribution for X-bar, the bounds of which form...

The mean of the distribution of truck weights is 20,000 lbs with a standard deviation of 2,000 lbs. Assume that the distribution approximates a Bell curve. Suppose you pick a single truck at random. What is the probability that the weight will be between 21,000 and 22,000 miles? Use area from a value. (Show a screen shot for your answer.) Use the central limit theorem to the following questions. Suppose you pick a group of 16 trucks instead. What would...

2. The human body temperature has an average of 98.6° F and standard deviation of 0.62° F. [10pts] a. State the Central Limit Theorem. b. Find the probability that 1 randomly selected person has less than 98.2° F. c. If 106 people are randomly selected, find the probability that the average temperature for the sample is 98.2° F or lower. d. Given the results, what can you conclude about this event?

Let X be the lifetime of an electronic device. It is known that the average lifetime of the device is 767 days and the standard deviation is 121 days. Let x¯ be the sample mean of the lifetimes of 157 devices. The distribution of X is unknown, however, the distribution of x¯ should be approximately normal according to the Central Limit Theorem. Calculate the following probabilities using the normal approximation. (a) P(x¯≤754)= Answer (b) P(x¯≥784)= Answer (c) P(749≤x¯≤784)= Answer

A company claims that the average lifespan of a bicycle tire that they manufacture is 1200 miles. You randomly and independently collect a sample of 31 of these tires and find that the average distance these tires lasted was 1125.7 miles, with a standard deviation of 275 miles. You suspect the company is overstating how long their tires last. You formulate your suspicion as a left tailed hypothesis test. Your null hypothesis is "the average lifespan of these tires is...
