The US Department of Justice presents the rape and sexual assault rate as the number of such crimes per 1,000 females aged 12 years and older. If in a representative sample 4,000 females 583 reported completed rape in their lifetime, what would be the rape rate per 1,000 females in the United States??
A researcher wants to identify the average number of hours spent by senior high school students playing online games per day. From a sample of 100 senior high students, an average of 6 hours was determined. What is the parameter? O a. average number of hours spent by senior high school students playing online games per day Ob. a sample of 100 senior high students Oc. an average of 6 hours Od. all senior high school students
Data on pull-off force (pounds) for connectors used in an automobile engine application are as follows: 79.9 75.1 78.2 74.1 73.9 75.0 77.6 77.3 73.8 74.6 75.5 74.0 74.7 75.9 72.2 73.8 74.2 78.1 75.4 76.3 75.3 76.2 74.9 78.0 75.1 76.8 If necessary, round all intermediate calculations to four decimal places (e.g. 12.3456). (a) Calculate a point estimate of the mean pull-off force of all connectors in the population (Round the answer to four decimal places (e.g. 90.2353).) (b) Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the strongest 50% (Express the answer to two decimal place (e.g. 90.15).) (c) Calculate the point estimate of the population variance (Round the answer to three decimal places (e.g. 3.567).)

Part 2 1. Using the data sheet, determine if there was a difference between individuals who resistance train and individuals who do not resistance train for peak force of the dominant arm. a. Create a figure that includes the Average Peak Force for resistance-trained and the Average Peak Force for non-resistance trained participants for the dominant arm. b. Complete a t-test (two samples) to compare the Average Peak Force between resistance-trained and non-resistance trained participants for the dominant arm. Report the p value and interpret if there was a significant difference. c. What do these results tell us about our ability to produce force (strength) if we do or do not resistance train?

Two of your friends at School A and School B heard that you are taking a statistic course and would like your help with their chemistry lab reports. They both have 10 independent measurements of the specific gravity of a compund from different populations. Their results are: School A 4.50 3.82 3.50 3.93 3.35 3.65 3.67 3.44 3.20 3.80 School B 5.10 4.34 2.40 4.90 1.23 3.89 1.87 5.30 4.65 4.70 They would like to know whether the data show convincingly that there is a significant difference between the two report given a Significance level of 1%. What is your conclusion?
The Centre of Student Experience (CSE) needs to know freshmen' average spending at UNIMY on campus supplies, food, stationery, and books.

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 33 of the 38 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 94 of the 111 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 #P2 Hy:P1 =P2 O B. Ho: P1 =P2 H1: P1 P2 H1: P1 #P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? the null hypothesis.

A researcher interested in the lobster fishery analyzed a population of lobsters living in shallow waters off a cove in Maine. He measured the length of all the lobsters in the population. The data is shown below. Min 11.4 Table 1: Lengths of Maine Lobsters (cm); (N=2,581) Quartile 1 Q2 (Med) 23.4 41.1 Quartile 3 56.8 Max 71.5 What is true of a lobster that is 56.9 cm in length? O It's bigger than all but one of the lobsters in that area About half the lobsters in the area are bigger, and about half are smaller that that lobster It is bigger than about 25% of the lobsters in that area O About 75% of the lobsters are smaller than that lobster
