Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she
has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. Let Χ be the random variable representing the time it takes her to complete one review.Assume Χ is normally distributed.Let be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews. A. Find the probability that the mean of a month’s reviews will take Yoonie from 3.5 to 4.25 hrs. Sketch the graph, labeling
and scaling the horizontal axis. Shade the region corresponding to the probability.
b. P(________________) = _______
C. Find the 95th percentile for the mean time to complete one month's reviews. Sketch the graph.
D. The 95th Percentile =____________
Answer the shopping cart had a velocity of 3 m/s as it moved across the parking lot.
Step-by-step explanation:
The time taken for this displacement is 5.2 seconds. So, the velocity of the shopping cart can be estimated by the above mentioned relation as, velocity of shopping cart = 15.6 m / 5.2 s = 3 m/s.
