H0: p = 0.5 HA: p ( 0.5 Calculate Test Statistic: z. p-value: p-value This null hypothesis can be rejected at any value of ( (significance level) greater than 20.76%. 7. The MATWES procedure was designed to measure attitudes toward women as managers. High scores indicate negative attitudes and low scores indicate positive attitudes.

You take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B. Let m1 represent the true average price of apartments in town A and m2 the average price in town B. 9. Suppose we were to use the pooled t-test. The t statistic for comparing the mean ...

2. Calculate your test statistic. Collect your data, and calculate the value of the test statistic based on these data. The test statistic may be an estimator of the parameter involved in the hypotheses, or it may be related to the estimator. Examples: the sample mean and its z-score. The statistician needs to know the distribution of the test ...

The P-value (or “observed significance level”) of a test is the probability of observing as extreme (or more extreme) of a value of the test statistic than we did observe, if H0 was in fact true. The P-value gives us an indication of the strength of evidence against H0 (and for Ha) in the sample.

c 11. Given that the critical value that the test statistic is to be compared with is equal to 1.645 at a 90% significance level, which of the following statements are true? a. The researcher should reject the null hypothesis at the 90% significance level. b. The researcher might be able to reject the null hypothesis at the 95% level of ...
