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

A continuous random variable is normally distributed. The probability that a value in the distribution is greater than 47 is 0.3085. Find the probability that a value in the distribution is less than 47.

Assume the random variable binomial distribution with the given probability of obtaining a success. Find the following probability , given the number of trials and the probability of obtaining a success. Round your answer to four decimal places . P(X > 1), n = 5, p = 0.8

The probability that a customer will order a nonalcoholic beverage is .41 find the probability that in a sample of 5 customers,  none of the 5 will order a nonalcoholic beverage. Round your answer to 4 decimal places

A certain disease has an incidence rate of 0.2%. The false negative rate is 8%, and the false positive rate is 3%. Calculate the probability that a person who tests positive actually has the disease. 0.0848 Note: The incidence rate is the probability that a random person gets the disease. The false negative rate is the probability of getting a negative result given that the person has the disease. The false positive rate is the probability of getting a positive result given that the person does not have the disease.

In a random sampleof 5 couples who plan to marry, find the probability of the following. Round intermediate calculations and final answers to three decimal places. At least 3 couples will have a destination wedding.         P(at least 3 couples will have a destination wedding)=
