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%

M12 Q9

What is the optimal time for a scuba diver to be on the bottom of the ocean? That depends on the depth of the dive. The U.S. Navy has done a lot of research on this topic. The Navy defines the "optimal time" to be the time at each depth for the best balance between length of work period and decompression time after surfacing. Let x = depth of dive in meters, and let y = optimal time in hours. A random sample of divers gave the following data.

x 16.1 26.3 31.2 38.3 51.3 20.5 22.7
y 2.68 2.18 1.48 1.03 0.75 2.38 2.20

Interpretation

For a 1 meter increase in depth, the optimal time increases by an amount that falls within the confidence interval.

For a 1 meter increase in depth, the optimal time decreases by an amount that falls outside the confidence interval.     

For a 1 meter increase in depth, the optimal time decreases by an amount that falls within the confidence interval.

For a 1 meter increase in depth, the optimal time increases by an amount that falls outside the confidence interval.

You wish to test the following claim (HaHa) at a significance level of α=0.005α=0.005. For the context of this problem, μd=μ2−μ1μd=μ2-μ1 where the first data set represents a pre-test and the second data set represents a post-test.

      Ho:μd=0Ho:μd=0
      Ha:μd>0Ha:μd>0

You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n=264n=264 subjects. The average difference (post - pre) is ¯d=3.6d¯=3.6 with a standard deviation of the differences of sd=20.4sd=20.4.

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

  • less than (or equal to) αα
  • greater than αα



This test statistic leads to a decision to...

  • reject the null
  • accept the null
  • fail to reject the null



As such, the final conclusion is that...

  • There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is greater than 0.
  • There is not sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is greater than 0.
  • The sample data support the claim that the mean difference of post-test from pre-test is greater than 0.
  • There is not sufficient sample evidence to support the claim that the mean difference of post-test from pre-test is greater than 0.
