A company makes auto batteries. They claim that 81% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p be the proportion in a random sample of 70 such batteries that are good for 70 months or more. a. What is the probability that this sample proportion is within 0.02 of the population proportion? Round your answer to two decimal places b. What is the probability that this...

A report announced that the median sales price of new houses sold one year was $221,000, and the mean sales price was $272,400. Assume that the standard deviation of the prices is $100,000. Complete parts (a) through (d) below. if you select samples of n=2, describe the shape of the sampling distribution of X Choose the correct answer below. A. The sampling distribution is skewed to the right (because population was skewed to the right), but less skewed to the...
