Problem Set 1: Chi Square Goodness of Fit (7 pts) A teacher believes that the percentage of students at her high school who go on to college is lower than the rate in the general population of high school students. The rate in the general population is 69.7% (BLS, 2017). In the most recent graduating class at her high school, the teacher found that of 104 who graduated, 61 of those went on to college. |

4. The following data set represent the percentage of gold from two different
locations:
Location A
| 23.6 | 22.4 | 18.9 | 29.8 | 22.7 | 25.4 | 17.5 | 14.2 | 29.4 | 26.1 | 24.1 | 22.3 |
Location B
5.0 6.1 2.3 2.1 7.8 9.2 4.1 2.5 4.2 9.9 1.0 1.2
b) Now consider the two locations as a single data set. What are the mean and the standard deviation of the gold percentage for this data set?
c) Using the empirical rule, determine what range of values captures the middle 68% of the data for the combined data set. Give the lower and upper limit of this range.
d) What is the actual percentage of data points that falls between these two values? Why is it different from your answer of part c?

When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 10%. Let X = the number of defective boards in a random sample of size n = 20, so X ~ Bin(20, 0.1). (Round your probabilities to three decimal places.)
(a) Determine P(X ≤ 2).
b. Determine P(X ≥ 5).
c. Determine P(1 ≤ X ≤ 4).
d. What is the probability that none of the 20 boards is defective?
e. Calculate the expected value and standard deviation of X. (Round your standard deviation to two decimal places.)
| expected value | = boards |
| standard deviation | = boards |

Compute the yield to maturity for each bond. b. Plot the zero-coupon yield curve (for the first five years). c. Is the yield curve upward sloping, downward sloping, or flat?

6. Research Question: Is there a higher percentage of Christians among CSU students than among USC students?
To test this I set up the hypothesis test
H0 : pCSU = pUSC Ha : pCSU > pUSC
This test gave a p-value of 0.023.
(a) Give your conclusion in context for this test using α = 0.05. (Your conclusion should be written so that a lay person could understand.)
(b) Give your conclusion in context for this test using α = 0.01. (Your conclusion should be written so that a lay person could understand.)
(c) Using the same sample data as in the hypothesis test, would a 95% confidence interval for pCSU − pUSC include the value 0? Explain.
Suppose someone you know and their spouse has been trying to start a family for a couple of years. The wife thinks she may be pregnant, so there will be a pregnancy test. Suppose the test has the hypotheses
H0 : Wife is pregnant.
Ha : Wife is not pregnant. (

Eric wants to estimate the percentage of elementary school children who have a social media account. He surveys 500 elementary school children and finds that 250 have a social media account. Identify the values needed to calculate a confidence interval at the 99% confidence level. Then find the confidence interval.
