The table below gives a two-way table showing the answers to this question as well as the education level of the respondents. A person's education is categorized as HS (high school degree or less), Some (some college), or College (college graduate or higher). Is the level of a person's education related to how the person feels about one true love? If there is a significant association between these two variables, describe how they are related. chi-square statistic = i 103.2 Agree 361 Disagree 555 Don't know HS Some College Total Total 163 469 18 28 197 786 30 934 660 1013 721 1810 76 2607 Table 1 Educational level and belief in One True Love Round your answer for the chi-square statistic to one decimal place, and your answer for the p-value to three decimal places.arrow_forwardWhich is the right option?arrow_forward

This student is arguing against school choice. Which statement best serves as the writer’s claim? School Choice: Good Intentions, Extremely Harmful Since the desegregation of schools in America, the question of school choice has been at the center of many heated debates. Some argue that charter schools or school choice programs put public schools at risk. Those people also argue that some neighborhood schools would suffer if kids had the freedom to commute to schools of their choice. Others argue that parents should control where their students learn, even if it means going to a school outside of their zoned area. However, school choice highlights problems with the inequities in the school system. All schools should provide students with quality education and school choice prevents that from happening.arrow_forwardA Ph.D. graduate has applied for a job with two colleges: A and B. The graduate feels that she has a 60% chance of receiving an offer from college A and a 50% chance of receiving an offer from college B.

Let A = receiving an offer from college A, and let B = receiving an offer from college B. a. What is the probability that both colleges will make her an offer? b. What is the probability that at least one college will make her an offer? c. If she receives an offer from college B, what is the probability that she will not receive an offer from college A?arrow_forward
- Suppose a university has only one women's softball scholarship remaining for the coming year. The final two players that the university is considering are Allison Fealey and Emily Janson. The coaching staff has concluded that the speed and defensive skills are virtually identical for the two players, and that the final decision will be based on which player has the best batting average. Crosstabulations of each player's batting performance in their junior and senior years of high school are as follows. Outcome Allison Fealey Junior Senior Hit 15 80 No Hit 25 175 Total At-Bats 40 255 Outcome Emily Janson Junior Senior Hit 75 35 No Hit 130 85 Total At-Bats 205 120 A player's batting average is computed by dividing the number of hits a player has by the total number of at-bats. Batting averages are represented as a decimal number with three places after the decimal. (Round your answers to three decimal places.) (a) Calculate the batting average for each…arrow_forwardA company has 30 employees, including a director. The lowest salary among the 30 employees is $22,000. The director’s salary is $180,000, which is more than twice as much as anyone else’s salary. Decide for each of the following statements about the 30 salaries whether it is true, false, or you cannot tell on the basis of the information at hand. • The median salary is below $60,000.• The average salary is below $60,000.• If all salaries are increased by $1,000, that adds $1,000 to the average.• If the director’s salary is doubled, and all other salaries remain the same, that increases the average salary.• If the director’s salary is doubled, and all other salaries remain the same, that increases the median salary.• The standard deviation of the salaries is larger than $180,000arrow_forward(Devore: Section 2.3 #41) An ATM personal identification number (PIN) consists of four digits, each a 0, 1, 2, ..., 8 or 9, in succession. (a) How many different possible PINs are there if there are no restrictions on the choice of digits? (b) According to a representative at the author's local branch of Chase Bank, there are in fact restrictions on the choice of digits. The following choices are prohibited: (i) all four digits identical (ii) sequences of consecutive ascending or descending digits, such as 6543 (iii) any sequence starting with 19 (birth years are too easy to guess). So if one of the PINs in (a) is randomly selected, what is the probability that it will be a legitimate PIN (that is, not be one of the prohibited sequences)? (c) Someone has stolen an ATM card and knows that the first and last digits of the PIN are 8 and 1, respectively. He has three tries before the card is retained by the ATM (but does not realize that). So he randomly selects the 2nd and 3rd digits for…arrow_forward
