The time it takes to complete an online survey is uniformly distributed over the range of 10.1 minutes to 16 minutes. Calculate the probability that it takes a person between 11.2 and 11.9 minutes to complete the survey.

The mean percent of childhood asthma prevalence in 43 cities is 2.39%. 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 2.6%? Interpret this probability. Assume that o = 1.31%. The probability is (Round to four decimal places as needed.) 4

Find the indicated probability and interpret the result. From 1975 through 2020, the mean annual gain of the Dow Jones Industrial Average was 653. A random sample of 33 years is selected from this population. What is the probability that the mean gain for the sample was between 400 and 800? Assume σ = 1540. The probability is ☐ (Round to four decimal places as needed.)
