Answer:
A. False
B. True
C. True
D.True
Step-by-step explanation:
A. False . The significance level or alpha is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. 0.01 alpha is better than 0.05 alpha . 0.01 indicate a 1% risk of rejecting the null hypothesis when it is true .
B. True . If the p-value is less than alpha, we reject the null hypothesis . Therefore statistically significant.
C . True . If the p-value is less than alpha, we reject the null hypothesis
D. True . Alpha will be greater than p-value . Therefore we will reject .
Answer
Relative risk= 0.742
Odds ratio= 0.745
Detailed calculation shown in diagram:
Answer:
(15/16)" + (3/32)" = (33/32)" = 1.03125" of material from the rod. since each pin needs to be (15/16)" = 0.9375" we have enough rod for one more pin.
