Assume that blood pressure readings are normally distributed with a mean of 116 and a standard deviation of 4.8. If 36 people are randomly selected, find the probability that their mean blood pressure is less than 118. A) 0.9938
B) 0.9998
C) 0.8615
D) 0.0062

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
