- A particular fruit's weights are normally distributed, with a mean of 228 grams and a standard deviation of 20 grams. The heaviest 4% of fruits weigh more than how many grams? Give your answer to the nearest gram.arrow_forwardFor a sample of 23 operating rooms taken in a hospital study, the mean noise level was 37.9 decibels, and the standard deviation was 7.6. Find the 95% confidence interval of the true mean of the noise levels in the operating rooms. Assume the variable is normally distributed. Use a graphing calculator and round the answers to at least one decimal place.arrow_forwardA particular fruit's weights are normally distributed, with a mean of 363 grams and a standard deviation of 17 grams.The heaviest 19% of fruits weigh more than how many grams?Give your answer to the nearest gram.arrow_forward
- A particular fruit's weights are normally distributed, with a mean of 585 grams and a standard deviation of 18 grams.If you pick 15 fruits at random, then 17% of the time, their mean weight will be greater than how many grams?Give your answer to the nearest gram.arrow_forwardA particular fruit's weights are normally distributed, with a mean of 696 grams and a standard deviation of 25 grams. If you pick 26 fruits at random, then 4% of the time, their mean weight will be greater than how many grams? Give your answer to the nearest gram.arrow_forwardUse z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallestarrow_forward

If you pick 25 fruits at random, then 5% of the time, their mean weight will be greater than how many grams? Give your answer to the nearest gram.arrow_forwardA successful basketball player has a height of 6 feet 11 inches, or 211 cm. Based on statistics from a data set, his height converts to the z score of 5.17. How many standard deviations is his height above the mean?arrow_forward
