Given P(E) = 0.26, P(F) = 0.48, and P(E and F) = 0.11, what is P(E or F)?

Suppose that 18% of a random sample of 2307 Miami residents said that they will donate blood in 2021. What is the proportion of all Miami residents who will donate blood in 2021? The decimals in your answer must be rounded to three decimal places. O A. 0.167, 0.193) O B. (0.186, 0.201) OC. (0.164, 0.196) O D. (0.192, 0.211)

Travis took the ACT (μ=19.50,σ=7) and recieved a percentile of 67. What was his z score? What was his raw score? If he performed equally well on the SAT, what would his SAT score be?

In a survey of 1150 adult males, 805 said they use the Internet. In a survey of 1050 females, 746 said they use the Internet. At a = 0.05, can you reject the claim that the proportion of Internet users are the same for both groups?

For each problem, select the best response. (a) For a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice. The correlation is r = 0.2. If you had measured tail length in centimeters instead of millimeters, what would be the correlation? (There are 10 millimeters in a centimeter.)A. 0.2/10 = 0.02B. 0.2C. (0.2)(10) = 2D. None of the above. (b) A study found a correlation of r = -0.61 between the gender of a worker and his or her income. You may correctly concludeA. women earn less than men on average.B. this is incorrect because r makes no sense here.C. an arithmetic mistake was made. Correlation must be positive.D. women earn more than men on average.E. None of the above.   Speak

Use the following information to answer the next two exercises: Suppose one hundred eleven people who shopped in a special t-shirt store were asked the number of t-shirts they own costing more than $19 each. 79. The percentage of people who own at most three t-shirts costing more than $19 each is approximately: a. 21 b. 59c. 41d. Cannot be determined 80. If the data were collected by asking the first 111 people who entered the store, then the type of sampling is: cluster simple random stratified convenience

In a sample of 58 men, 44 said that they had less leisure time today than they had 10 years ago. In a sample of 58 women, 36 women said that they had less leisure time today than they had 10 years ago. At a=0.10, is there a difference in the proportions? Use p, for the proportion of men with less leisure time. Part: 0 / 6

Given P(E) = 0.23, P(F) = 0.34, and P(E and F) = 0.08, what is P(E or F)?

you have two results for p= technically which one is the correct reference?
