Suzie simplified the following expression. What mistake did she make? 2(3 + 9x) - 2x 6 + 9x - 2x 6 + 7x
Levart [38]

2(3 + 9x) - 2x

= 6 + 9x - 2x <----------------mistake right here

= 6 + 7x

Correct:

Expanding by using distributive property

2(3 + 9x) - 2x

= 2* 3 + 2 * 9x - 2x

= 6 + 18x - 2x

= 6 + 16x

Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the t
Korvikt [17]

Answer:

The <em>p</em>-value of the test is 0.0512.

Step-by-step explanation:

The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.

In this case the output of the t-test_ind method from scipy module is provided as follows:

Output = (-1.99, 0.0512)

The first value within the parentheses is the test statistic value.

So the test statistic value is, -1.99.

And the second value within the parentheses is the <em>p</em>-value of the test.

So the <em>p</em>-value of the test is 0.0512.
