In testing Null hypothesis H0:β2=10 H 0 : β 2 = 10 and alternative hypothesis H0:β2≠10 H 0 : β 2 ≠ 10 using a 1% significance level, you find a p-value of 0.05. What should you conclude? Select one:
a. There is not sufficient evidence to reject null hypothesis (H0) so we maintain the null hypothesis by default.
b. H0 is not true, and thus β2=c. β 2 = c .
c. H0 should be rejected and is unlikely to be true since the p-value < 0.1.
d. It is impossible to know for sure, but there is 0.05 probability that

A hypothesis testing: H0: p=0.49 HA: p<0.49.
A hypothesis testing: H0: p=0.49 HA: p<0.49. We conduct a survey with sample size n=171 and have pˆ=0.39. With α=0.05, do you reject or fail to reject the Null hypothesis? Enter 1 if you "reject the Null hypothesis" and 0 if you "fail to reject the null hypothesis".Note:1- Enter either 0 or 1 in the box. The box does not accept text as an answer. Your answer should be either 0 or 1 and no other answers will be accepted.

Explain what the below mathematical information means in written paragraph or two : NULL HYPOTHESIS H0: ALTERNATIVE HYPOTHESIS Ha: Not all means are equal. alpha=0.05 Test statistic F=16.821 P value=0.000 Since P value SMALLER than the level of significance therefore SIGNIFICANT. Decision: DO NOT REJECT H0. Conclusion: There is sufficient evidence to conclude that the marks obtained by the Brothers are different.

True or False The model used for hypothesis testing of proportions is called a two-proportion z-test. True or False Beta (β) is the significance level which determines if the null hypothesis is rejected. True or False In business, the p-value is one of several factors in determining whether or not to reject a null hypothesis. True or False We could make a decision to reject a null hypothesis on a very low p-value or a very high z score.
