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:
1 : 3
Step-by-step explanation:
1st Half: 9
2nd Half: 2(9)
Ratio = 2nd : 1st+2nd
9 : 9+2(9)
9 : 9 + 18
9 : 27
1 : 3
Dividing:- (1.75 * 10^18) / (6.25 * 10^15)
= (1.75 / 6.25) * (10^18 / 10^15)
= 0.28 * 10^3
= 280 Answer
