Question

Compute a 95% confidence interval?

Hypothesis: Students spend an average of 35 hours per week studying

H0 : μ = 35

H1 : μ ≠ 35

Sample data:

X̄= 27.71 hours

n=34

p= 0.815

Test values:

z= -4.751

p= 0.0001

np > 10 n(1-p) > 10

34*0.815 = 27.71

34*(1-0.815) = 6.29

When engaging in weight control (fitness/fat burning) types of exercise, a person is expected to attain about 60% of their maximum heart rate. For 20-year-olds, this rate is approximately 120 bpm. A simple random sample of 100 20-year-olds was taken, and the sample mean was found to be 107 bpm with a standard deviation of 45 bpm. Researchers wonder if this is evidence to conclude that the expected level is actually lower than 120 bpm. To determine this, we test the following hypotheses O H: 120, Ha: 120 H: 120, Ha: 120 OH:120, Ho: <120 OH:120, Ha:μ = 120

The National Assessment of Educational Progress (NAEP) includes a mathematical test for eighth-grade students. Scores on the test range from 0 to 500. Suppose that you give the NAEP test to an SRS of 2500 eighth-graders from a large population in which the scores have mean u = 282 and standard deviation o = 110. The mean x will vary if you take repeated samples. Suppose that we computed a 90% confidence interval for u. Which is true? This 90% confidence interval could have either a smaller or a larger margin of error than the 95% confidence interval. This varies from sample to sample. This 90% confidence interval would have a smaller margin of error than the 95% confidence interval. This 90% confidence interval would have a larger margin of error than the 95% confidence interval. This 90% confidence interval would have the margin of error as the 95% confidence interval.
