Answer:
C.) -5 and 5
Step-by-step explanation:
Plug in -5 & 5 separately for x.
Plug in -5 for in the equation. Remember to follow PEMDAS. First solve for power, then multiplication.
2(-5)² = 50
2(25) = 50
50 = 50 (True).
Plug in 5 into the equation for x. Remember to follow PEMDAS. First solve for power, then multiplication.
2(5)² = 50
2(25) = 50
50 = 50 (True).

In the fourth step, he didn’t put the “negative” sign for 4.
Assuming that the null hypothesis is true, then<u> p-Value</u> is the probability of observing a value of the test statistic that is at least as extreme as the value actually computed from the sample data.
Step-by-step explanation:
<u>The p-value is the probability that a random sample that is selected produces as the value of the test statistic is at least as extreme as the observed value when H0 is true.</u>
<u>The p-value as measure of how surprising our result is if the null hypothesis is true.</u>
So ,we can state that- Assuming that the null hypothesis is true, then<u> p-Value</u> is the probability of observing a value of the test statistic that is at least as extreme as the value actually computed from the sample data.
2.15 + 2.5 = 2.65
2.65 + 3.85 = 6.40
If it is 0.5
6.40 + 0.5 = 0.9
If you meant 0.05
6.40 + 0.05 = 6.45
If you meant 5 (as in the whole number)
6.40 + 5 = 11.40
hope this helps
