1. The distribution of heights of adult females: We assume that height is normally distributed with a population mean of 65 inches and a population standard deviation of 4 inches. 2. The distribution of heights of adult males: We assume that height is normally distributed with a population mean of 70 inches and a population standard deviation of 5 inches. a. Above what Z-score value does 2.5% of the normal distribution fall? Using the formula for Z-scores and the Z-score...

A large study of the heights of 1170 adult men found that the mean height was 71 inches tall. The standard deviation was 8 inches. If the distribution of data was normal, what is the probability that a randomly selected male from the study was between 63 and 87 inches tall? Use the 68-95-99.7 rule (sometimes called the Empirical rule or the Standard Deviation rule). For example, enter 0.68, NOT 68 or 68%. Round your answer to three decimal places....

Exercise: An ethologist is interested in determining the average weight of adult Olympic marmots. It would be expensive and impractical to trap and measure the whole population, so a random sample of 16 adults is trapped and weighed. The sample has a mean of 7.3 kg and a standard deviation of 0.48. It is known from past studies that the distribution is approximately normal with standard deviation of 0.5. Find the 95% confidence interval for the average weight of adult...
