An analyst of professional football games believes that the average number of running plays per game has increased from the previous average of 32 plays per game. Assume number of running plays per game follows a normal distribution. A sample of 16 games this year produced an average of 34.5 running plays per game with a standard deviation of 4.5 running plays per game. Perform a hypothesis test using a 1% level of significance. 44. What are the null and alternative hypotheses? a) H0: μ ≥ 32 vs. H1: μ < 32 b) H0: μ ≤ 32 vs. H1: μ > 32 c) H0: μ > 32 vs. H1: μ ≤ 32 d) H0: μ < 32 vs. H1: μ ≥ 32 e) H0: μ = 32 vs. H1: μ ≠ 32 45. What is the critical value of the test? a) 2.575 b) 2.33 c) 2.22 d) 2.602 e) 2.947 46. What is the appropriate conclusion? a) Reject H0 . We can conclude that the average number of running plays has increased. b) Reject H0 .We cannot conclude that the average number of running plays has increased. c) Do not reject H0 .We cannot conclude that the average number of running plays has increased. d) Do not reject H0 .We can conclude that the average number of running plays has increased. e) Do not reject H0 .We can conclude that the average number of running plays has not increased
Common symptoms of gastritis are: A. epigastric pain. B. belching. C. diarrhea. D. a and b.
Write a program in the machine code (use the code presented in the lecture and given after the problems). Write machine code that calculates the multiplication of positive numbers 'm' (multiplicand) and 'n' (multiplier). 'm' is stored in memory cell F016, and 'n' is stored in memory cell F916. Store the result of the multiplication in memory cell CB16. 'm' and 'n' are in 2's-complement code. Remember: Multiplication can be done by a series of additions. Assume that there are no overflow issues, whatsoever. Hint: Do not forget the memory cell addresses!
3. Given \( z_{i} \in \mathbb{C} \) for \( i=1, \ldots, 5 \) such that \( \left|z_{1}\right|=\cdots=\left|z_{5}\right|=2 \) and \( \left|z_{1}+\cdots+z_{5}\right|=8 \), compute \( \left|z_{1}^{-1}+\cdots+z_{5}^{-1}\right| \).
The psychological process that social psychologists believe explains “bystander effects” (e.g., effects observed in a study of bystander intervention by Latané and Darley) is: A. diffusion of responsibility B. cognitive dissonance C. mere exposure D. the fundamental attribution error
Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 13. Use the empirical rule to determine the following.

(c) What percentage of people has an IQ score greater than 139? (a) % (Type an integer or a decimal.)
2. Bob took out a loan of $30,000 to do some renovations to his factory and was given an interest rate of 5.48% compounded semi-annually. He agreed to make quarterly payments of $1,700 to pay off the loan. a) How many quarterly payments will Bob have to make to pay off the loan? (5 marks)
