Question

Question 22 3 pts Suppose you are interested in testing a null hypothesis and the p-value associated with the test statistic is 0.004. As a result, you should o reject the null hypothesis at the 5-percent level of significance, but not at the 1- percent level of significance. do not reject the null hypothesis at the 5-percent level of significance, but do reject the null at the 1-percent level of significance. o do not reject the null hypothesis at the 5-percent or 1-percent levels of significance. o reject the null hypothesis at both the 5-percent and 1-percent levels of significance. Question 23 3 pts Suppose that the underlying population is normally distributed. Suppose further that a random sample of 36 observations on a single variable has a sample mean of 4 and a sample standard deviation of 3. That standard error of the sampling distribution is O 0.75 O 2 0 1 O 0.5 Question 24 3 pts Suppose that the underlying population is normally distributed. From a random sample of 16 individuals from this population, the sample mean is 8 and the sample standard deviation is 10. Suppose someone claims that the true population mean is 3. The value of the t-test statistic is and the null hypothesis be rejected at the 10- percent level of significance. o 1.2: cannot 1.8; can 03.2; cannot 2; can

Answer 1

classmate Date Page reject the O null 22: of p-value value is less than 0.05, null hypotheses, and if p-value is greater than 0.05, we do not reject hypothesis , at all significance levels Lo So here pvalie So, we refect the null hypothesis at both 5-percent and a percent level of lignificance 0.004 <0.05 7 cance. Option (d) is correct answer Q23 standard error = ( population Standard deviation) n= Observations 36 3 Option d) is correct answer. Q29 t-stalistic 3-M S.E 2 Standard error S.D lo Sn √16 x = sample mean =8 M = pople population mean = 3 8-3 5x2 = 2 t-statistic 5 2 this option d) is connect ! can be rejected As t-statistic is equal to 2, it is at 10% significance level Scanned by TapScanner
