If my result is significant, do I reject my null hypothesis?: The t-value is 2.76273. The p-value is .006739. The result is significant at p < .05 Also, do I reject null for this information below too?: The t-value is 21.65739. The p-value is < .00001 (p-value ≈ 0). The result is significant at p < .05.
Which of the following statements is correct? Batting Average Strikeout Percentage 0.328 3.2 0.290 7.6 0.340 4.0 0.248 8.6 0.367 3.1 0.269 11.1 A. We have evidence that a greater percentage of strikeouts is associated with a lower batting average since P < 1%. OB. We do not have evidence that a greater percentage of strikeouts is associated with a lower batting average since P < 1%. C. There is a statistically positive correlation between percentage of strikeouts and batting average. D. Both A and C are correct.
A hypothesis test performed by a student has a Z value of 1.63. Is this test statistically significant at a 5% level? Yes, it is significant because z is larger than 1.645. Yes, it is significant because z is smaller than 1.645. No, it is not significant because z is smaller than 1.645. Yes, it is significant because z is smaller than 1.960.

After asking a sample of her students for their opinion of her class, the statistics professor calculates the test statistic z = 2.69 for the hypothesis test H: p = 0.80 H: p > 0.80, where p is the proportion of all students in the class who enjoyed the class. Which of the following is true? a The P-value is .9964 and conclude that more than 80% of the students enjoyed her class. b The P-value is .0036 and conclude that more than 80% of the students enjoyed her class. c The P-value is .9964 and conclude that less than 80% of the students enjoyed her class. d The P-value is .0036 and conclude that less than 80% of the students enjoyed her class.
Decide whether you would reject or fail to reject the null hypothesis in the following situations: = 3.50, sD = 1.10, n = 12, a = .05, two-tailed test 95% CI = (0.20, 1.85) t = 2.98, t* = −2.36, one-tailed test to the left 90% CI = (−1.12, 4.36)
A television manufacturer claims that (at least) 90% of its TV sets will not need service during the first 3 years of operation. A consumer agency wishes to check this claim, so it obtains a random sample 100 purchasers and asks each whether the set purchased needed repair during the first 3 years after purchase. Let p be the sample proportion of responses indicating no repair (so that no repair of n = is identified with a success). Let p denote the actual proportion of successes for all sets made by this manufacturer. The agency does not want to claim false advertising unless sample evidence strongly suggests that p < 0.9. The appropriate hypotheses are then Ho: p = 0.9 versus H: p < 0.9. %3D

Suppose there is a claim that a certain population has a mean, p, that is 5 or more. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Hy and the alternative hypothesis, H, as follows. H: u<5 Suppose you also know the following information. The value of the test statistic based on the sample is -1.572 (rounded to 3 decimal places). The p-value is 0.058 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Normal Distribution Step 1: Select one-tailed or two-tailed. o One-tailed O Two-tailed 0.3 Step 2: Enter the test statistic. 02 (Round to 3 decimal places.) Step 3: Shade the area represented by the p- value. (b) Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value…
Can you help me determine the P-value approach at the α=0.10 level of significance to test the hypotheses for the following equation?
