Since t = 4.0 > 1.690, reject Ho and conclude that the new cars average more than 42 miles per gallon. b. p-value < 0.005, therefore reject Ho (area to the right of t = 4.0 is almost zero) PTS: 1 TOP: Hypothesis Tests 44. The average starting salary of students who graduated from colleges of Business in 2009 was $48,400.

Chi-square = 0.855 + 3.744 + 0.276 + 1.204 = 6.079 4. What do we know about the P-value for testing the null hypothesis that the probability of complaining is the …
'p' value of 0.000?
P-Value = 0.000. This tells us that the sample estimates of Pearson correlation of Day and Weight is -0.998 based on 14 observations. When test for significance, a low p-value rejects the null that rho=0 and we conclude that the sample estimates just did not come from the noise. There is a meaningful linear relationship between the two variables.

A significance test yields a P-value of 0.0101. (a) Explain what it would mean for the null hypothesis to be true in this setting. (b) Interpret the P-value in context. 13. Lefties. Refer to Exercise 3. In Simon’s SRS, 16 of the students were left-handed. A significance test yields a P-value of 0.2184. What conclusion would you make if α = 0.10?

You obtain a P-value of 0.0742. Which of the following is true? (a) You have failed to obtain sufficient evidence against . H. 0. (b) At the 5% significance level, you have proved that . H. 0 is true. (c) At the 5% significance level, you have failed to prove that . H.

(ii) P-value = 2P(Z>4.844)=2(0)=0. Since the P-value ( (=0.05, reject H0. Conclude that it is different for two groups of residents. Population characteristics: Ratio of the two population variances, or standard deviations, . X and Y's are random sample from a normal distribution. and are the population variances for X's and Y's, respectively.

The probability shaded greater than 0.905 is (1-0.8186) =0.1814. p-value = 0.1814. p-value is not less than alpha. So, we fail to reject Ho. 61. B The assumptions of the hypothesis test for a proportion are the data must be categorical, data must come from a random sample, np> 15 and n(1-p…
