Suppose there is a 27.4% probability that a randomly selected person aged 40 years or older is a jogger. In addition, there is a
29.3% probability that a randomly selected person age 40 years or older is male, given that he or she jogs. Required:
a. What is the probability that a randomly selected person age 40 years or older is male and jogs?
b. Would it be unusual to randomly select a person aged 40 years or older who is male and jogs?
The probability that a random selected person of age 40 years or older is a jogger is
The probability that a random selected person of age 40 years or older is a male given that he/she jogs is
Generally the probability that a randomly selected person age 40 years or older is male and jogs
Generally it would be unusual because the probability that a randomly selected person age 40 years or older is male and jogs is greater than 0.05[border line for statistical significance]
