3)Recently a community college offered a 2-credit course to help students with math anxiety. At the beginning of the course, each student took a 30-question survey (called MARS-S); the higher the score, the more anxiety experienced by the student. The nine students remaining in the class took the same survey at the end of the course. The before and after scores for each of the nine students who completed the course are shown below.

Compute the correlation between before and after scores for these students. (Assume the correlation conditions have been satisfied and round your answer to the nearest 0.001.)

Suppose a study of n=269 students was conducted asking their weeknight study time. The mean response was 137 min. with an assumed KNOWN standard deviation of 65 min. The hypothesis of interest is whether the mean study time is GREATER than 120 min.

What is the value of the test statistic?

Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38

Do students reduce study time in classes where they achieve a higher midterm score? In a Journal of Economic Education article (Winter 2005), Gregory Krohn and Catherine O’Connor studied student effort and performance in a class over a semester. In an intermediate macroeconomics course, they found that “students respond to higher midterm scores by reducing the number of hours they subsequently allocate to studying for the course.” Suppose that a random sample of n = 8 students who performed well on the midterm exam was taken and weekly study times before and after the exam were compared. The resulting data are given in Table 11.5. Assume that the population of all possible paired differences is normally distributed.

95% CI for mean difference: (4.24889, 10.50111)

T-Test of mean difference = 0 (vs not = 0): T-Value = 5.58, P-Value = .0008

(a) Set up the null and alternative hypotheses to test whether there is a difference in the true mean study time before and after the midterm exam.

(b). Above we present the MINITAB output for the paired differences test. Use the output and critical values to test the hypotheses at the .10, .05, and .01 level of significance. Has the true mean study time changed? (Round your answer to 2 decimal places.)

(c) Use the p-value to test the hypotheses at the .10, .05, and .01 level of significance. How much evidence is there against the null hypothesis?

A week before a certification election, a WalShop store manager (who resides in Walnut) walks by a Rancho Cucamonga church in order to observe a union organizing meeting she read about on a bulletin board in the employee cafeteria.  According to her rough count, approximately a hundred of the 250 employees at the store were attending.  She looks for familiar faces from the sidewalk outside (and makes notes of what she observes) but does not attempt to make contact with anyone going inside the church.    After several nervous employees called the manager’s presence out to the union supporter, Arturo Cruz, Cruz comes outside and orders the manager to leave.  After a brief argument, the manager departs but not before wagging her finger at the church and shouting “Unions will be the death of us all!”   The union loses the election by a close margin (120 in favor of certification, 130 against).  Shortly thereafter, the union files an unfair labor charge against WalShop claiming that the supervisor’s presence and words constituted a “threat of reprisal” and thereby invalidated the election.  In testimony before the Administrative Law Judge (ALJ), the supervisor states she was merely in the neighborhood and walked by out of curiosity.  Management tells the ALJ that it neither ordered nor was aware of the supervisor’s action at the time it occurred. A regional vice president admitted, however, that he received a memo from the manager the day after the meeting describing what she had seen (including the names of some prominent employees in attendance) but claims to have taken no action based on the memo.   Does the union need to prove that an unfair labor practice charge occurred in order to invalidate the election?  Without regard to whether an unfair labor practice can be proven, should the election be ruled invalid (be sure to name the appropriate test the NLRB uses for judging elections and analyze the facts to determine whether that test can be proven)?  Be sure to explain your answer.

The car that you are driving in the snow has a mass of 10,000 kg and the coefficient of friction is 0.20.

a) What is the maximum velocity that the car can drive around an unbanked corner in the snow if the curve has a radius of 200 meters?

b) Now the road becomes straight after you exit the curve. You brake suddenly without slipping. How long (in time) will it take for the car to come to a stop? Assume you are initially traveling at the speed calculated in part (a).

c) After using the brakes, how far (final distance) would the car travel before it came to a stop in part (b)?

A) A chemist titrates a 25.0 mL sample of 0.191 M benzoic acid (C6H5COOH) against a 0.100 M solution of NaOH. The overall reaction is shown by the equation below: $$C6​H5​COOH(aq)+NaOH(aq) C6​H5​COONa(aq)+H2​O(l) The Ka value for benzoic acid is 6.28 × 10–5. Calculate the pH at the start of the titration, before any NaOH has been added. Give your answer correctly to two places after the decimal.

B) What will the pH be when 12.0 mL of 0.100 M NaOH has been added to the weak acid solution? Give your answer to two places after the decimal.

A school district developed an after-school math tutoring program for high school students. To assess the effectiveness of the program, struggling students were randomly selected into treatment and control groups. A pre-test was given to both groups before the start of the program. A post-test assessing the same skills was given after the end of the program. The study team determined the effectiveness of the program by comparing the average change in pre- and post-test scores between the two groups. During the course of the program, some students in both the treatment and control groups either dropped out of school or they moved away with their families. Could this attrition potentially distort the estimated effectiveness of the tutoring program? Defend your answer.
