A random sample of 33 of these cities is selected. What is the probability that the mean childhood asthma prevalence for the sample is greater than 2.8% ? Interpret this probability. Assume that a = 1.29%
The mean height of women in a country (ages 20-29) is 63.8 inches. A random sample of 70 women in this age group is selected. What is the probability that the mean height for the sample is greater than 64 inches? Assume a=2.56. www The probability that the mean height for the sample is greater than 64 inches is (Round to four decimal places as needed.)
The height of women ages 20-29 is normally distributed, with a mean of 64 2 inches. Assume a=2.8 inches. Are you more likely to randomly select 1 woman with a height less than 66.1 inches or are you more likely to select a sample of 15 women with a mean height less than 66.1 inches?
