Suppose IQs are normally distributed with a mean of 100 and a standard deviation of 16. a) If one person is randomly selected, what is the probability that the person’s IQ is higher than 90 but lower than 115? b) If eight people are randomly selected, what is the probability that the sample mean IQ is higher than 90 but lower than 115?
Claim: The standard deviation of pulse rates of adult males is more than 12 bpm. For a random sample of 129 adult males, the pulse rates have a standard deviation of 12.3 bpm. Find the value of the test statistic.
Claim: The standard deviation of pulse rates of adult males is more than 10 bpm. For a random sample of 149 adult males, the pulse rates have a standard deviation of 10.5 bpm. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)
Claim: The standard deviation of pulse rates of adult males is more thanmore than 12 bpm. For a random sample of 133 adult males, the pulse rates have a standard deviation of 12.6 bpm. Find the value of the test statistic. The value of the test statistic is
(i) A car test for people older than 16 is appox normally distributed with mean = 100 and standard Deviation = 15. Calculate the probability that a random person has a test score of 105 or more? (ii) What is the mean and standard deviation for a random sample of 60 people. (iii) what is the probability that the average test score of a random sample of 60 people is 105 or more?
The standard Deviation of pulse rates of adult males is less than 12 Bpm. For a random sample of 126 adult males, the pulse rates have a standard deviation of 10.8 bpm. Find the value of test statistic Step by step resolution
Claim: The standard deviation of pulse rates of adult males is less than 12 bpm. For a random sample of 131 adult males, the pulse rates have a standard deviation of 11.8 bpm. Find the value of the test statistic.
6.4.5-T Question Help Assume that females have pulse rates that are normally distributed with a mean of u = 73.0 beats per minute and a standard deviation of o = 12.5 beats per minute. Complete parts (a) through (c) below. a. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 79 beats per minute.
