**Problem Description:**According to a report, 62.5% of murders are committed with a firearm.**Questions:**(a) If 100 murders are randomly selected, how many would we expect to be committed with a firearm?(b) Would it be unusual to observe 68 murders by firearm in a random sample of 100 murders? Why?---**(a)** We would expect [blank] to be committed with a firearm.**(b)** Choose the correct answer below.- **A.** No, because 68 is between μ − 2σ and μ + 2σ.- **B.** No, because 68 is greater than μ + 2σ.- **C.** Yes, because 68 is between μ − 2σ and μ + 2σ.- **D.** Yes, because 68 is greater than μ + 2σ.- **E.** No, because 68 is less than μ − 2σ.

We have given that p=62.5%=0.625 , q=1-p=1-0.625=0.375 n=100 X~Binomial(n=100,p=0.625)

College Degree Recipients A survey of 800 recent degree recipients found that 158 received associate degrees; 451, bachelor degrees, 21 first-professional degrees; 154, master degrees; and 16, doctorates. Is there sufficient evidence to conclude that at least one of the proportions differs from a report which stated that 23.3% were associate degrees; 51.1%, bachelor degrees; 3%, first professional degrees; 20.6%, master degrees; and 2%, doctorates? Use =α0.10.
According to a report, 71.9% of murders are committed with a firearm. (a) If 400 murders are randomly selected, how many would we expect to be committed with a firearm? (b) Would it be unusual to observe 312 murders by firearm in a random sample of 400 murders? Why? (a) We would expect to be committed with a firearm. (b) Choose the correct answer below. A. Yes, because 312 is greater than u + 20. B. No, because 312 is between u - 20 and H+ 20. O C. No, because 312 is greater than p + 2o. D. No, because 312 is less than u - 20. E. Yes, because 312 is between u - 20 and u + 20.
In a memory test, the test subjects are given a large number and are asked to memorize it. Historical records show that 80% of test subjects pass the test. To pass the test, a subject must exactly repeat all the digits in the number after two hours. A random sample of 625 people to take the memory test is going to be chosen. Let p be the proportion of people in the sample who pass the test. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of P. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(P >0.84), which is the probability that more than 84% of the people in the sample pass the test. Round your answer to four decimal places. 0 X
Rachel Green, a fashion buyer at Ralph Lauren, wanted to know which seasonal clothing line Ralph Lauren customers prefer. She randomly selected 200 Ralph Lauren customers to survey about their seasonal preferences. She asked the following question: "Which seasonal clothing line is your favorite: spring, summer, fall, or winter?" The results were as follows: Spring: 10 Summer: 11 Fall: 149 Winter: 20 Based ONLY on this information (do not try to infer anything else!), answer the following questions. Did sampling bias occur? Why or why not? Did response bias occur? Why or why not? Did nonresponse bias occur? Why or why not?
A group of students at a local university were asked about their status (undergraduate, graduate, or non-degree seeking) and how they get to campus (walk/bike or car/bus/etc.). The results are summarized in the table below. How do you get to Campus? Walk/Bike Car/Bus/etc. Total Undergraduate 80 20 100 Graduate 40 10 50 Non-degree Seeking 10 40 50 Total 130 70 200 Suppose we choose a person at random from this sample. Which of the following statements is true? (A) If the person uses a car/bus/etc. to get to campus, then he or she is more likely to be a non- degree seeking student than a degree seeking student (undergraduate or graduate). (B) If the person is an undergraduate, then he or she is more likely to use a car/bus/etc. to get to campus than to walk/bike to campus. (C) The person is more likely be a graduate student if he or she uses a car/bus/etc. to get to campus than if he or she walks/bikes to campus. (D) The person is more likely to use a car/bus/etc. to get to campus than…
2. A study for adverse reactions assigned adults at random to one of two common pain relievers (ibuprofen and acetaminophen). It was found that out of 733 adults who were administered ibuprofen, 103 of them experienced an adverse reaction, and out of 732 adults who were administered acetaminophen, 85 of them experienced an adverse reaction. Let p1 denote the proportion of adults who experience an adverse reaction when taking ibuprofen and let p2 denote the proportion of adults who experience an adverse reaction when taking acetaminophen. Suppose we want to answer the following questions. i) Test, at the 3% level of significance, whether the proportion of adults who experience an adverse reaction when taking ibuprofen is greater than the proportion of adults who experience an adverse reaction when taking acetaminophen. ii) Calculate the 97% confidence interval for p1 - P2. The table below provides the information needed to perform the hypothesis test: Value x1 103.0000 85.0000 733.0000…
A Statistics instructor wishes to know the average age (in month) of his 200 students. He decides to choose 25 students from the class and ask them for their age. All 200 names are put in a hat and 25 names are then chosen at random (without replacement). The average age of the students chosen is observed to be 231 months. The group of 25 students is known as what?
In a survey, it was found that 80% of adults operate the flusher of toilets in public restrooms with their foot. (a) If 300 adults are randomly selected, how many would we expect to flush toilets in public restrooms with their foot? (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? (a) We would expect (Type a whole number.) adults to flush toilets in public restrooms with their foot. (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? Choose the correct answer below. O A. Yes, because 255 is greater than u + 2o. O B. No, because 255 is greater than u + 20. O C. Yes, because 255 is between u - 20 and u+ 20. O D. No, because 255 is less than u- 20. O E. No, because 255 is between u -20 and u+ 20.

(b) Would it be unusual to observe 73 murders by firearm in a random sample of 100 murders? Why? (a) We would expect to be committed with a firearm. (b) Choose the correct answer below. A. Yes, because 73 is greater than u + 20. B. No, because 73 is less than u - 20. C. Yes, because 73 is between u - 20 and u + 20. D. No, because 73 is between u - 20 and u + 20. E. No, because 73 is greater than u + 20.

Refer to the following scenario. A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs should be located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 120 people living in Gastown and finds that 21 have an annual income that is below the poverty line. For each of the following statements, specify whether the statement is a correct interpretation of the 95% confidence interval for the true proportion of Gastown residents living below the poverty line. A. 17.50% (21/120) of Gastown residents are living below the poverty line. ? B. There is a 95% probability that the true proportion of Gastown residents who are living below the poverty line equals 21/120. C. If another random sample of 120 Gastown residents is drawn, there is a 95% probability that the sample proportion of Gastown residents who are living below…
