The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luggage, which in turn will result in higher fuel costs. For a sample of 8 flights, the correlation between the number of passengers and total fuel cost was 0.634. a. State the decision rule for 0.010 significance level: H0: ρ ≤ 0; H1: ρ > 0. (Round your answer to 3 decimal places.) b. Compute the value of the test statistic. (Round your answer to 2 decimal places.) c. Can we conclude that the correlation in the population is greater than zero? Use the 0.010 significance level. H0. It is to conclude that there is positive association in the population between the two variables.

Prior to assessment of the outcome, the researchers did a manipulation check. Members of Groups 1 and 2 rated the attractiveness (on a 1 to 9 scale, with 9 being the most attractive) of the person in the photo. They reported that for the attractive photo, M = 7.53; for the unattractive photo, M = 3.20, F(1, 108) = 184.29. Was this difference statistically significant (using a = .05)?
The National Association of Home Builders provided data on the cost of the most popular home remodeling projects. Sample data on cost in thousands of dollars for two types of remodeling projects are as follows.
In a study to determine if the nitrogen content of the soil in Wyoming is significantly different from the nitrogen content of the soil in North Dakota, 34 independent random soil samples from Wyoming and 36 from North Dakota were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the nitrogen content of the soil in Wyoming is significantly different from the nitrogen content of the soil in North Dakota, at the 1% significance level. H0:μw=μnHa:μw≠μn The test statistic is t0=2.653 t0.005=±2.382
In a study to determine if the nitrogen content of the soil in Wyoming is less than the nitrogen content of the soil in North Dakota, 27 independent random soil samples from Wyoming and 32 from North Dakota were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the nitrogen content of the soil in Wyoming is less than the nitrogen content of the soil in North Dakota, at the 1% significance level. H0:μw≥μnHa:μw<μn The test statistic is t0=−1.53 t0.01=−2.663

In order to determine if the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, independent random samples of 28 southern flowing streams and 35 northern flowing streams were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the average bacteria content of southern flowing streams is less than the average bacteria content of northern flowing streams, at the 5% significance level. H0:μs≥μnHa:μs<μn t0=−0.108 t0.05=−1.999 Select the correct answer below: No; the test statistic is less than the critical value. Yes; the test statistic is greater than the critical value. No; the test statistic is greater than the critical value. Yes; the test statistic is less than the critical value.

They reported that for the attractive photo, M = 7.53; for the unattractive photo, M = 3.20, F (1, 108) = 184.29. Was this difference statistically significant (using = .05 )? The p value F(1,108) = 184.29 is less than 0.0001. Therefore, the difference is statistically significant because the p value is much less than .05 What was the effect size for the difference in (2a)?
The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luaggage, which in turn will result in higher fuel costs. For a sample of 13 flights, the correlation between the number of passengers and total fuel cost was .37. Is it reasonable to conclude that there is positive association in the population between the two variables? H0: p≤0 Ha: p >0 Use the 5% significant level, what is the p-value?____________ What is your decision regarding H0 or the hull hypothesis? Reject or Do not Reject______________ Draw a conclusion. Specifically, what does this indicate about the question?
