Individuals who have a certain gene have a 0.50 probability of contracting a certain disease. Suppose that 1,940 individuals with the gene participate in a lifetime study. What is the standard deviation of the number of people who eventually contract the disease? Round your answer to 2 decimal places.

standard deviation = √npq

n = sample size = 1940

p = 0.50

q = 1 - p = 0.50

I'll let you take it from here.

The time it takes for climbers to reach the highest point of a mountain is normally distributed with a standard deviation of 0.75 hours. If a sample of 35 people is drawn randomly from the population, what would be the standard error of the mean of the sample
