Using traditional methods it takes 8.8 hours to receive a basic driving license. A new license training method using Computer-Aided Instruction (CAI) has been proposed. A researcher used the technique on 17 students and observed that they had a mean of 8.4 hours with a variance of 2.89. Is there evidence at the 0.1 level that the technique performs differently than the traditional method? Assume the population distribution is approximately normal. Step 4 of 5 : Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
In a random sample of males, it was found that 25 write with their left hands and 217 do not. In a random sample of females, it was found that 58 write with their left hands and 450 do not. Use a .05 significance level to test the claim that the rate of left-handedness among males is less than that among females. Identify the test statistic.z=?

Reject or Fail to Reject the null hypothesis. There is or is not sufficient evidence to support the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment.
If you have a hypothesis test with alpha = 0.1, which of the following P-Values does NOT imply statistical significance? %3D 0.084 0.005 0.117 0.056 A researcher wants to find out if there is a significant difference between men and women in the average number of tattoos that a person has. After doing the statistical analysis, the researcher finds that the p- value is 0.003. If the chosen significance level is 0.05 (5%), which of the following statements is the best interpretation of this p-value?? | The results are statistically significant. | The results are not statistically significant. | The magnitude of a p-value. has no impact on statistical significance.
In 1990, the average duration of long-distance telephone calls originating in one town was 9.4 minutes. A long-distance telephone company wants to perform a significance test to determine whether the average duration of long-distance phone calls has changed from the 1990 mean of 9.4 minutes. The hypotheses are: H0: μ = 9.4 minutes HA: μ ≠ 9.4 minutesSuppose that the results of the sample lead to non-rejection of the null hypothesis. Classify that conclusion as a Type I error, a Type II error, or a correct decision, if in fact the mean duration of long-distance phone calls has changed from the 1990 mean of 9.4 minutes. Choose the best asnwer below: A. Neither B. Type I error C. Type II error D.No error
In a multiple regression analysis, two independent variables are considered and the sample size is 26. The regression coefficients and the standard errors are as follows; b1 = 1.468 sb1 = 0.89 b2 = -1.084 sb2 = 0.88 Use the 0.05 significance level; Conduct a test hypothesis to determine whether either independent variable has a coefficient equal to 0. (negative amounts should be indicated by a minus sign) (round to 3 decimal places) Would you consider deleting either variable from the regression equation? *See image
Using traditional methods it takes 8.2 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 26 students and observed that they had a mean of 8.0 hours with a variance of 2.89. Is there evidence at the 0.1 level that the technique reduces the training time? Assume the population distribution is approximately normal. Step 3 of 5: Specify if the test is one-tailed or two-tailed.
