A retail manager in a discount store wants to establish a policy of the number of cashiersto have on hand and also when to open a new cash register. The first step in this processis to determine the rate at which customers arrive at the cash register. One day, the man-ager observes the following times (in minutes) between arrivals of customers at the cashregisters:0.12.62.90.51.21.84.83.31.70.21.52.04.20.61.02.60.93.41.70.4a Plot a CDF based on these data.b What kind of theoretical distribution do you think would be appropriate for thesedata? Why?c Calculate the sample mean and sample standard deviation of the data, and use theseto estimate parameters for the theoretical distribution chosen in part b.d Plot a few points from the CDF of your theoretical distribution, and draw a smoothcurve through them. How does this theoretical curve compare to the data-based CDF?

Given information: The data represents the times between arrivals of customers at the cash…

Answer the following questions using the separate rates X1,..., X20 and Y1,..., Y20 shown in Figure 1. (a) Carry out the calculations for a test of the hypotheses that the mean U.S. mortality rate On remained the same or increased from 2005 to 2015 against the alternative that the mean mortality rate decreased. State the hypotheses, test statistic, rejection region, and p-value. Do not interpret the conclusion of the test. (b) Compute a 99% confidence interval for the change in mean heart rate mortality. Do not interpret the interval.

AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
