- A mathematics placement test is given to all incoming freshmen at the College of Accountancy. A student who receives a grade below 35 is denied admission to the regular mathematics course and placed in a remedial class. The placement test scores and the final grades for 20 students who took the regular course were: Test Score Course Grade Test Score Course Grade 50 53 35 41 35 61 40 56 55 68 65 36 35 11 60 70 90 79 35 59 90 54 80 91 60 48 60 71 40 47 55 53 50 68 65 57 50 79 60 71 a. Plot a scatter diagram. b. Find the equation of the regression line to predict course grades from placement test scores. c. Graph the line on the scatterd. d. If 60 is the minimum passing grade, below which placement test score should students in the future be denied admission to this course?arrow_forwardMaria has two routes, E and W, she can take when commuting to work. Both routes go through a railroad crossing, and sometimes she needs to stop at the crossing to allow trains to pass. She claims that the proportion of times she needs to stop when taking route E is different from the proportion of times she needs to stop when taking route W. She conducted the following hypothesis test at the significance level of α=0.10. H0:pE=pWHa:pE≠pW In the hypotheses, pE represents the proportion of times she needs to stop at the crossing when using route E, and pWrepresents the proportion of times she needs to stop at the crossing when using route W. All conditions for inference were met, and the resulting p-value was 0.37. Which of the following is the correct decision for the test? The p-value is less than α, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the…arrow_forwardOf the claims shown below, determine which are valid statistical hypotheses and which are not. For those claims that are not valid, explain why. (a) p = 0.6 (b) x > 42 (c) µ < 87 1 (d) σ 2 6= 36 (e) pˆ1 = ˆp2 (f) µ1 6= µ2 (g) x < y (h) σ 2 1 σ 2 2 > 4arrow_forward
- C. A college requires an IQ of 120 or more for entrance. From what percentage of the population must it draw its students?arrow_forwardSolve the problems by following the steps and procedures in hypothesis testing. PRACTICE QUESTIONarrow_forwardCalculate the prevalence for each of the following questions. Responses must be in cases per 1,000 persons. You must explicitly state the context of your answer by including the disease/outcome, the place of interest, and the time/duration (for example: “There were 12 cases of measles per 1,000 students at UCONN in 2012”). Assume 3,465 women, 60-74 years old, were screened for presence of osteoporosis at a major women’s health fair held in Phoenix, AZ from 1/3 – 1/10 of last year. A total of 974 cases of osteoporosis were identified at screening. What is prevalence of osteoporosis in group?arrow_forward

Let the proportion of patients that need a root canal be p. If the dental assistant wanted to know if the proportion of patients that need a root canal is more than 20%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.20; Ha: p<0.20 H0: p>0.20; Ha: p=0.20 H0: p=0.20; Ha: p>0.20 H0: μ=0.20; Ha: μ>0.20arrow_forward
