A researcher believes that about 73% of the seeds planted with the aid of a new chemical fertilizer will germinate. He chooses a random sample of 165 seedsand plants them with the aid of the fertilizer. Assuming his belief to be true, approximate the probability that more than 117 of the 165 seeds will germinate.Use the normal approximation to the binomial with a correction for continuity.Round your answer to at least three decimal places. Do not round any intermediate steps.(If necessary, consult a list of formulas.)

Solution-: Given: n=165,p=0.73 (Or 73%) We want to find, P(more than 117 of the 165 seeds will…

Answered: A researcher believes that about 73% of…

Assuming a population is normally distributed, calculate the probability that a random member of the population falls between 3 standard deviations below the mean and 1 standard deviation below the mean. In other words in mathematical notation: P(-3 < z < -1) Enter your answer in decimal form. For example, 75% should be entered as 0.75.
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.
