For which of the given p-values would the null hypothesis be rejected when performing a level 0. 05 test?.
Masja [62]

Using a significance level of 0.05, the null hypothesis would be rejected for p-values less than 0.05.

<h3>What is the relation between the p-value and the conclusion of test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

  • If it is more, the null hypothesis is not rejected.
  • If it is less, it is rejected.

Hence, the null hypothesis would be rejected for p-values less than 0.05.

4. Allen is showing his work in simplifying -8.3 + 9.2 - 4.4 + 3.7. Identify and explain any errors in his work or in his reason
Vladimir79 [104]

Answer:

-8.3 + 9.2 - 4.4 + 3.7

= -8.3 + 9.2 + (-4.4) + 3.7            {Additive inverse}

= -8.3 + (-4.4) + 9.2 + 3.7            {Commutative Property}

= [ -8.3 + (-4.4] + [ 9.2 + 3.7]       {Associative property}

=  - 12.7 + 12.9

= 0.2
