Answer:

The answer is option 3.

Step-by-step explanation:

Option 3 is correct because it has parentheses around 40 - x, but not the cube itself or the 3rd power if you didn't know what I meant. Anyway, the reason this is correct is because if you look at any order of operations, you will notice that parentheses always comes before powered numbers, so if you were to choose, say option 2, it would be a completely different answer than option 3, not to mention wrong also.

The p-value for a two-sided test of the null hypothesis H0: μ = 10 is 0.06.(a) Would a 95% confidence interval for μ include the

Answer:

a) Yes b) No

Step-by-step explanation:

Given that the p value for a two-sided test of the null hypothesis H0: μ = 10

is 0.06

a) $p value = 0.06.\\Confidence level = 95%\\Significance level = 100-95 = 5%\\Alpha = 0.05\\\\p \geq \alpha is true$

Hence we accept null hypothesis

This implies that 10 will be within the confidence interval of 95%

b) If confidence level = 90%

$\alpha = 0.10\\p value = 0.06\\p \leq 0.10$

So we have to reject null hypothesis.

So we do not have 10 in the confidence interval

The reason is the lower the confidence level, the narrower the confidence interval. In this case, 10 has gone outside the narrower interval hence we get this.
