Your high school crush is working with a breed of guinea pig in which the side on which the hair parts down the back is inherited, and it can either be on the left or the right. Left-parting appears to be dominant in this system. S/he/they crosses true-breeding parents that are phenotypically left-parters and gets a generation of right-parters. Inbreeding the F1 produces a generation that consists entirely of left-parters.

f. How is this trait transmitted?

g. What are the genotypes of the parents and the genotypic ratios of the F1 and the F2?

h. What was the genotype of the mother of the original female parent?

The scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=535.4 and standard deviation σ=28.

(a) What is the probability that a single student randomly chosen from all those taking the test scores 542 or higher?
ANSWER:

For parts (b) through (d), consider a simple random sample (SRS) of 25 students who took the test.

(b) What are the mean and standard deviation of the sample mean score x, of 25 students?
The mean of the sampling distribution for x is:
The standard deviation of the sampling distribution for x is:

(c) What z-score corresponds to the mean score x of 542?
ANSWER:

(d) What is the probability that the mean score x of these students is 542 or higher?
ANSWER:

At the beginning of the 2016 school year, Britney Logan decided to prepare a cash budget for the months of September, October, November, and December. The budget must plan for enough cash on December 31 to pay the spring semester tuition, which is the same as the fall tuition. The following information relates to the budget:

a. Prepare a cash budget for September, October, November, and December. Enter all amounts as positive values except an overall cash decrease which should be indicated with a minus sign.

b. Are the four monthly budgets that are presented prepared as static budgets or flexible budgets?

c. Brittany can see that her present plan   sufficient cash. If Logan did not budget but went ahead with the original plan, she would be $   at the end of December, with no time left to adjust.

A recent 10-year study conducted by a research team at the Medical School was conducted to assess how age, blood pressure, and smoking relate to the risk of strokes. Assume that the following data are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period. For the smoking variable, define a dummy variable with 1 indicating a smoker and 0 indicating a nonsmoker.

What action might the physician recommend for this patient?

The scores of high school seniors on the ACT college entrance examination in a recent year had mean μ = 20.8 and standard deviation σ = 4.8. The distribution of scores is only roughly Normal.

(a) What is the approximate probability that a single student randomly chosen from all those taking the test scores 21 or higher? (Round your answer to four decimal places.)


(b) Now take an SRS of 25 students who took the test. What are the mean and standard deviation of the sample mean score x of these 25 students? (Round your answers to two decimal places.)

(c) What is the approximate probability that the mean score

x

of these students is 21 or higher? (Round your answer to four decimal places.)


(d) Which of your two Normal probability calculations in (a) and (c) is more accurate? Why?

The answer to (a) is more accurate because an individual score should have a distribution farther from Normal.The answer to (a) is more accurate because an individual score should have a distribution that is exactly Normal.    The answer to (a) is more accurate because an individual score should have a distribution closer to Normal.The answer to (c) is more accurate because x should have a distribution closer to Normal.The answer to (c) is more accurate because x should have a distribution that is farther from Normal.

Colby participates in a rocket-launch competition in her high school. The goal is to launch a rocket with mass m = 2.3 kg [5 lbs] to a height no less than 50-m (164 ft) above ground.

a) What is the minimum momentum of the rocket as it leaves the launch pad?

b) Colby figured out three possible propulsion mechanisms that differ by the generated force F (“thrust”) and the time interval ∆t during which the force acts on the rocket [“burn time”]: Force F [N] Time interval ∆t [s] Propulsion #1 161 0.41 Propulsion #2 233 0.37 Propulsion #3 532 0.12 What is Colby’s best choice for the propulsion mechanism? Explain your reasoning!

c) Colby is excited about the successful launch of her rocket but is disappointed because the rocket is in air for only t1 = 3.1 s after the launch until it reaches the highest point. Explain Colby’s disappointment and calculate the air resistance acting on the rocket! Assume that the air resistance is constant.

d) Does Colby’s rocket meet the requirement of the contest?

e) The rocket returns to the ground at the time t2 = 6.5 s measured from the time of the launch. Calculate the impulse imparted on the rocket during the flight form the highest back to the ground. Find the velocity vector!] of the rocket just before it lands on the ground!

Personal Budget

At the beginning of the school year, Priscilla Wescott decided to prepare a cash budget for the months of September, October, November, and December. The budget must plan for enough cash on December 31 to pay the spring semester tuition, which is the same as the fall tuition. The following information relates to the budget:

a. Prepare a cash budget for September, October, November, and December. Enter all amounts as positive values except cash decrease which should be indicated with a minus sign.

Feedback

b. Are the four monthly budgets that are presented prepared as static budgets or flexible budgets?

Static

c. What are the budget implications for Priscilla Wescott?

Priscilla can see that her present plan will not provide  sufficient cash. If Priscilla did not budget but went ahead with the original plan, she would be $ short  at the end of December, with no time left to adjust.
