Do the percentage of positive Covid cases resulting in serious symptoms differ between sexes? nm = 700 randommales who had just tested positive for Covid were selected. Of these, xm = 226 wound up having serioussymptoms. nf=600 random females who had just tested positive for Covid were selected. Of these, xf = 150wound up having serious symptoms. Suppose Pm is the true proportion of males testing positive for Covid whowind up having serious symptoms. Suppose p, is the true proportion females testing positive for Covid who windup having serious symptoms. Pm and pf are unknown and we will examine relations between them based uponthese samples. Let pmhat be the sample proportion of selected males who wind up having serious symptoms. Letpfhat be the sample proportion of selected females who wind up having serious symptoms.a)Calculate an unbiased point estimate of Pm.b) We wish to construct a 94 % classical confidence interval for Pm.

A recent study of high school students shows the percentage of females and males who have an after-school job. A simple random sample of high school students was interviewed. The students were asked whether they worked after school. Of the 250 females, 58 answered yes, as did 113 of the 380 males. Part A: Construct and interpret a 95% confidence interval for the difference in population proportions of females and males who have an after-school job. Be sure to state the parameter, check conditions, perform calculations, and make conclusion(s). Part B: Does your interval from part A give convincing evidence of a difference between the population proportions? Explain.
When using a (1−α)%(1−α)% confidence interval for some population parameter, why do we write that we are, e.g., 90% confident rather than 90% sure?
You developed a simulation for the Walton bookstore example for company profits. According to your simulation results the mean profit is $204.13 with a standard deviation of $328.04. You want to build a 95% confidence interval of length $25 (i.e. the difference between the upper and lower limit of the confidence interval will be $25). Assume that the multiple for a 95% confidence level is 2. Compute the minimum number of replications required to build the desired confidence interval. a. 2000 to 3000 b.1000 to 2000 c. More than 4000 d. 3000 to 4000 e. Less than 1000
Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat.

A financial analyst wants to estimate the difference in the mean growth for all large- and small-cap stocks for the last 60 days. He selects a random sample of 30 large-cap stocks and 30 small-cap stocks from the large populations of large- and small-cap stocks. Are the conditions for constructing a 90% confidence interval for the difference in the true mean growth of all large- and small-cap stocks for the last 60 days met? Random: 10%: Normal/Large Sample:
8.1 Confidence Interval 1. Crop researchers are interested in the productivity of a new variety of corn. They plant 25 plots with randomly selected seeds of the new variety, record the yield in bushels per acre, and find that a 99% confidence interval for the true mean yield is 118 to 130 bushels per acre. (a) Interpret the confidence interval. (b) What is the point estimate that was used to create the interval? What is the margin of error? (c) Interpret the confidence level. (d) Based on the research, a marketer tells a possible customer that with this new variety of corn they can expect to receive more than 130 bushels per acre, on average. Use the confidence interval to evaluate this statement.
