Consider the hypothesis test Ho: o2 o2 against H₁: o < o respectively. Suppose that thesample sizes are n₁ = 5 and n₂ = 10, and that s2 = 23.2 and s2 = 28.8. Use a = 0.05. Test thehypothesis and use the confidence interval to support the conclusionO a. Because 0.1666 < 0.806. Do not reject the null hypothesis.O b. None among the choicesO c. Because 0.1666 < 0.806. Do not reject the null hypothesis. Because 1 is contained within the interval, there is no significant differences in the variancesO d. Because 0.1666 <0.806. Reject the null hypothesis.

(a)A random sample of 25 college males was obtained and each was asked to report their actual height and what they wished as their ideal height. A 95% confidence interval for µd = average difference between their ideal and actual heights was 0.8" to 2.2". Based on this interval, which one of the null hypotheses below (versus a two-sided alternative) can be rejected? all the above c. H0: µd = 1.5 H0: µd = 0.5 b. H0: µd = 1.0 H0: µd = 2.0 (b)Which of the following is a correct form of an alternate hypothesis for paired data? H1: μd = p H1: μ1 ≠ μ2 H1: μd > 0 H1: μ1 = μ2 (C)Which of the following is always the null hypothesis for two sample proportions? d. H0: p1 = 3 H0: p1 < μ2 H0: p1 ≠ p2 H0: p1 = p2
In a test of H0: µ=27 against HA: µ ≠ 27, using α=.05, you get a 95% confidence interval with a lower limit of 26.7 and an upper limit of 28.3. What is your conclusion? a. fail to reject the null hypothesis. b. reject the null hypothesis. c.no enough information
For the hypothesis test, H0 : β = β0 vs. H1: β does not equal β1, suppose a valid likelihood ratio test (LRT) can be performed by rejecting the null hypothesis if 2{l(βhat) - l(β0))} > X^2 df, alpha. Which of the following is a valid (1-alpha)100 confidence interval (CI) for the β0? a. {β0: 2{l(βhat) - l(β0))} > Zalpha} b. {β0: 2{l(βhat) - l(β0))} <or equal to Zalpha} c. {β0: 2{l(βhat) - l(β0))} <or equal to X^2df, alpha} d. {β0: 2{l(βhat) - l(β0))} > X^2df, alpha}
From the results in the table: Question: Is there enough evidence to reject the null hypothesis that the ideal number of children is 2.0 if = 0.05? [Hint: the 2-sided p-value is provided in the cell labeled “Sig. (2-tailed)” and “.000” is equivalent to saying that the p-value is less than 0.001] b) If we were to calculate a 95% confidence interval for mu, would this interval contain the value 2.0?
An investigator has calculated a 95 percent confidence interval for a one-sample t test and found: P{97.0≤μ≤105.0}=0.95. If the investigator wants to test the hull hypothesis H0: μ=100,with α=0.05, the investigator should:
The test statistic of z=1.93 is obtained when testing the claim that p>0.2. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of α=0.10,should we reject H0 or should we fail to reject H0?

If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.6792 and ZSTAT=−0.47,what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? Since the p-value is Less than or Greater than or equal to a= , Reject , Do not reject H0.
