- A pharmaceutical company claims that after the clinical trials, it will release the first-ever cure for COVID-19. If they have committed an error of judgement, which type of error would they rather have, Type I or Type II? Why?How do high school students feel about trust and honesty in the workplace? A random sample of 9542 high school males, and a separate random sample of 11,420 high school females were asked whether they though trust and honest were essential in business and the workplace. Here are the results. Male Female Total Agree 9097 10935 20032 Disagree 445 485 930 Total 9542 11420 20962 a) Use PMACC (clearly label each step on your paper) to determine if there is a difference in the distribution of how high school students feel about trust and honest in business and the workplace among males and females. Use a significance level of 0.05. b) Show how to calculate the expected count for males who disagree.Using the normal distribution table, find the area of the given question. 1. Area belowu 2.

- 2. Is P (AIB) the same as P (BIA)?Your daughter is doing a case study with my husband to know which devices are used by the students in their online classes. As such, a survey was conducted to 100 engineering students at PUP. 54 of them use smartphone, 37 use laptop and 24 of the respondents use iPad. 21 of them use both smartphone and laptop. 13 of them use both iPad and smartphone. In addition to that, 18 of them use both iPad and laptop. Only 9 of the respondents use all the three devices in their online class. Those who do not have any devices are studying through modular approach. How many respondents are modular?Hello,For this question, I've solved (a)(b)(c) subparts.I don't know how to do the rest, which means subparts (d) and (e).Thank you for helping me this.
- 1.) This is not an incomplete question. It has all the components of the question that was asked. Please help explain. Need help from a prob and stats expert: Let arr86 be a binary variable equal to 1 if a man was arrested during 1986, and zerootherwise. You have a dataset of young men from California who were born in 1960 or1961 and have at least one arrest prior to 1986. You also have data on the proportion ofprior arrests that led to a conviction (pcnv), the average sentence served from priorconvictions in months (avgsen), months spent in prison since age 18 prior to 1986(tottime), months spent in prison in 1986 (ptime86), and the number of quarters (0 to 4)that the man was legally employed in 1986 (qemp86). You estimate the following linearprobability model (standard errors are in parentheses): The Standard Errors for the equation go in order for each independent variable of the equation, and are below. The equation is extended and is in two separte rows. All information is…An online clothing retailer is testing a new e-mail campaign by sending one version of the e-mail with the word “free” in the subject line (version A) to a group of 1,500 customers and another version of the e-mail with word “discount” in the subject line (version B) to a different group of 1500 customers. After tracking the responses to the two versions of the e-mail advertising, the retailer finds that 75 responded to version A and 105 responded to version B. At 0.05 significance level, can it be concluded that the response rate for version B is higher than the response rate to version A What is your decision? Enter “R” if your decision is to reject the null hypotheses. Enter “F” if the decision is fail to/do not reject the null hypotheses. Your answer (R/F) is: Which of the followings is the most appropriate conclusion for the hypotheses test? Enter the number corresponding to the most appropriate conclusion in the answer box. For example, if statement number 2 is the most…You may need to use the appropriate appendix table or technology to answer this question. In a recent poll six hundred adults were asked a series of questions about the state of the economy and their children's future. One question was, "do you expect your children to have a better life than you have had, a worse life, or a life about the same as yours?" Suppose the responses showed 251 better, 303 worse, and 46 about the same. Use the sign test and a = 0.05 to determine whether there is a difference between the number of adults who feel their children will have a better life compared to a worse life. State the null and alternative hypotheses. (Let p = the proportion of adults who feel their children will have a better life.) OH: P≥ 0.50 H₂: P 0.50 O H₂: P = 0.50 H₂: P = 0.50 O Ho: P < 0.50 H₂: P = 0.50 Find the value of the test statistic. (Round your answer to two decimal places.) z = -2.21 x Find the p-value. (Round your answer to four decimal places.) p-value = 0.0192 X What is…
- Suppose you are a basketball coach and you've taken some measures on your starting five players. The two measures that you're most interested in right now are scores on a two-minute jump shot test (x) and time in seconds on a shuttle run (y). You want to determine a couple of things:1) On which variable (jump shots or shuttle run time) are your starters more consistent? 2) For player #1, is she a faster runner or better at jump shots? 3) For player #4, is she a faster runner or better at jump shots? Player # Jump shot score (x) Shuttle run time (y) 1 17 37 2 20 45 3 4 59 4 34 48 5 22 42In this same passage, what is the explanatory variable and is it categorical or quantitative?Q7. A survey was conducted in which 100 males and, independently, 100 females were asked about their respective methods of transportation to work. Participants were asked whether they typically drive to work, use public transportation, or walk / bicycle. The results are given in the table below. Can the investigators conclude that males differ from females in their work commute tendencies? Show your work. Drive Public Transportation Walk or Bicycle 22 Females 71 7 Males 76 18 6 (a) Based on the assumption that female and male tendencies are alike, construct a table of expected frequencies. (b) Use a X² test to evaluate the assumption used in part a. Make sure you indicate which test you are using! (c) Interpret the result of part b in terms of the situation of the problem, without using any statistical language.
