standard deviation is s = 13.6 beats per minute. a. What is the difference between the pulse rate of 34 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 34 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 34 beats per minute significant?

a quantitative data set has mean 25 and standard deviation 2. approximately what percentage of the observations lie between 21 and 29?

c. IQ scores have a mean of 100 and a standard deviation of 16. Albert Einstein reportedly had an Q of 160. Arnav Sharma, a 12-year old boy gained a score of 162. 14 i. Convert Einstein's IQ score and Sharma's score to their corresponding Z-scores. ii. What is the difference between the Z-score of Einstein and Z-score of Sharma? iii. How many standard deviations are Einstein's and Sharma's Z-scores?

Plz explain. Ty

A value of 104.2 would be how many standard deviations above the mean, given a mean of 100, and a standard deviation of 5.6?

For a data set of the pulse rates for a sample of adult​ females, the lowest pulse rate is 39 beats per​ minute, the mean of the listed pulse rates is x overbar equals 77.0 beats per​ minute, and their standard deviation is sequals 21.2 beats per minute. a. What is the difference between the pulse rate of39 beats per minute and the mean pulse rate of the​ females? b. How many standard deviations is that​ [the difference found in part​ (a)]? c. Convert the pulse rate of39 beats per minutes to a z score. d. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly​ high, is the pulse rate of 39 beats per minute​ significant?

Use z scores to compare the given values. The tallest living man at one time had a height of 233 cm. The shortest living man at that time had a height of 89.9 cm. Heights of men at that time had a mean of 176.34 cm and a standard deviation of 5.47 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= height that was more extreme. (Round to two decimal places.) and the z score for the shortest man is z = the man had the

Find the percentage of area under a normal curve between the mean and the given number of standard deviations from the mean. This problem can be solved using technology or the table for the standard normal curve from your text.   −0.4 The percentage of area under the normal curve between the mean and −0.4 standard deviations from the mean is

A quantitative data set has mean 19 and standard deviation 2. Approximately what percentage of the observations lie between 17 and 21​?

Which of the following would be the most reasonable estimate for the weight of house cats?  (The population would be all house cats in the U.S., and the variable would be each cat's weight.) A. Mean = 10 pounds, standard deviation = 0 pounds. B. Mean = 10 pounds, standard deviation = 2 pounds. C. Mean = 10 pounds, standard deviation = 10 pounds. D. Mean = 2 pounds, standard deviation = 10 pounds.
