For a left-tailed test, the critical value of z so that a hypothesis test would reject the null hypothesis at 1% significance le
mars1129 [50]

Answer:

C.-2.33

Step-by-step explanation:

We are given that

Significance level, \alpha =1%=0.01

We have to find  the critical value of z  for a left-tailed test.

To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.

By using the z-table at significance level 0.01 for left-tailed test

The critical value of z at  1% significance level for left-tailed test

=-2.33

We get p-value by using z-critical value

P-value=0.0099<0.01

So, hypothesis  test would be reject the null hypothesis at  at 1% significance level.

Hence, the critical value of z=-2.33

Option C is true.

What is the solution to –2(8x – 4) &lt; 2x + 5?
dimulka [17.4K]

Answer:

A. x>\frac{1}{6}

Step-by-step explanation:

We are given the inequality, -2(8x-4)

On simplifying, we get,

-2(8x-4)

i.e. -16x+8

i.e. -18x

i.e. 6x>1

i.e. x>\frac{1}{6}

Thus, the solution of the inequality is x>\frac{1}{6}.

Hence, option A is correct.
