Round z-score to the nearest hundredth and then find the required A values using the table. The amount of time customers spend waiting in line at a bank normally distributed, with a mean of 3.0 minutes and a standard deviation of 7.5 minute. Find the probability that the time a customer spends waiting is as follows. (A) Less than 3.5 minutes and (B) less than 1.5 minutes.

Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mmHg) and the standard deviation is 5.6. Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. Part 1 of 3 If an individual is selected, find the probability that the individual's pressure will be between 117.3 and 120 mmHg. P(117.3 < X < 120) = 111 Part: 1/3 - Part 2 of 3 If a sample of 28 adults is randomly selected, find the probability that the sample mean will be between 117.3 and 120 mmHg. Assume that the sample is taken from a large population and the correction factor can be ignored. P(117.3 < X < 120) = Next Part olo Submit Assignment 2020 meoraw Thill LLC. All Rights Reserved.

The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 5.1 mm. Round values to 4 decimal places when possible. The mean of this distribution is   . The standard deviation is   . The probability that the round off error for a jumper's distance is exactly 4.3 is    P(x=4.3)=P(x=4.3)=   . The probability that the round off error for the distance that a long jumper has jumped is between 1.5 and 2.5 mm is    P(1.5<x<2.5)=P(1.5<x<2.5)=   . The probability that the jump's round off error is greater than 1.22 is    P(x>1.22)=P(x>1.22)=   . P(x>1.8∣x>0.5)=P(x>1.8∣x>0.5)=   . Find the 54th percentile.   Find the maximum for the lower quarter.

Suppose that the annual rate of return for a common biotechnology stock is normally distributed with a mean of 4% and a standard deviation of 4%. Find the probability that the one-year return of this stock will be positive. Round your answer to at least four decimal places. 0 X Ś
