It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.50 6.25 6.75 7.25 7.50 y 9 38 38 50 72 What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line?
Select one:
a. 89.9%
b. 10.1%
c. 94.8%
d. 0.3%
e. 1.0%

New York City is the most expensive city in the United States for lodging. The mean hotel room rate is $204 per night (USA Today, April 30, 2012). Assume that room rates are normally distributed with a standard deviation of $55. a. What is the probability that a hotel room costs $225 or more per night (to 4 decimals)? b. What is the probability that a hotel room costs less than $140 per night (to 4 decimals)? c. What is the probability that a hotel room costs between $200 and $300 per night (to 4 decimals)? d. What is the cost of the 20% most expensive hotel rooms in New York City? Round up to the next dollar. $ or

1) A well-known brokerage firm executive claimed that 30% of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that in a sample of 300 people, 34% of them said they are confident of meeting their goals.
Test the claim that the proportion of people who are confident is larger than 30% at the 0.10 significance level.
a) The null and alternative hypothesis would be:
H0:p≤0.3
H1:p>0.3
H0:p=0.3
H1:p≠0.3
H0:μ≥0.3
H1:μ<0.3
H0:μ≤0.3
H1:μ>0.3
H0:p≥0.3
H1:p<0.3
H0:μ=0.3
H1:μ≠0.3
2) The test is:
a) The test statistic is: _______ (to 3 decimals)
b) The p-value is: ________ (to 4 decimals)
c) Based on this we:
Reject the null hypothesis
or
fail to reject the null hypothesis

Hadey is approaching the housing situation from a different direction. He does a little research and learns that the mean rent for a one bedroom one bathroom apartment in Avocado Park is $1050 per month with a standard deviation of $125 per month.
A. The Avocado Park Housing Authority defines affordable housing as costing LESS than $900 per month for a 1B1R. Would such an apartment be considered unusual for the neighborhood?
B. Hadey wants to develop a new apartment building in Avocado Park offering 1B1R units at a price of $1000 per month. What effect would this new building have on the mean and standard deviation for 1B1R in Avocado Park?
C. If the Avocado Park Housing Authority issued vouchers to subsidize all 1B1Rs in the neighborhood and they lowered the rent on each unit by exactly $100 per month, what would the new mean and standard deviation be for the cost of renting a 1B1R in Avocado Park.

The left-field wall at a baseball park is 320 feet down the third-base line from home plate; the wall itself is 38 feet high. A batted ball must clear the wall to be a home run. Suppose a ball leaves the bat, 3 feet off the ground, at an angle of 45degrees. Use gequals32 ft/sec squared as the acceleration due to gravity and ignore any air resistance. Complete parts (a) through (d). (a) Find parametric equations that model the position of the ball as a function of time. (b) What is the maximum height of the ball if it leaves the bat with a speed of 120 miles per hour? Give your answer in feet. (c) What is the ball's horizontal distance from home plate at its maximum height? Give your answer in feet. (d) If the ball is hit straight down the third-base line, will it clear the wall? If it does, by how many feet does it clear the wall?
