If the probability of developing breast cancer among smokers is .05 for the study duration, then if you sample 100 smokers, how many do you expect to develop the disease? give the expected value +/- 1 standard deviation.

Explanation:

Given : The probability of developing breast cancer among smokers :

Sample size = 100

The mean  for binomial distribution is given by :-

The standard deviation for binomial distribution is given by :-

The expected number of people will develop the disease is given by :-

Explanation:

Responses may vary but should include some or all of the following information:

Reputable tests have three factors in common. They are all standardized, valid, and reliable. Standardized tests have scores that are compared to the results of other test takers. Valid tests cover the information that is being looked at. Reliable tests have results that remain consistent over multiple testings.
