Mathematics
1 answer:
kondor19780726 [428]3 years ago
8 0

Answer:

The correct ordered pair is (7,1)

Step-by-step explanation:

The given system has equations:

2x - 6y = 8....(1)

5x- 4y = 31....(2)

We make x the subject in the first equation to get:

x = 4  + 3y...(3)

Put equation 3 into equation 2 to get:

5(4 + 3y) - 4y = 31

Expand:

20 + 15y - 4y = 31

15y - 4y = 31 - 20

11y = 11

y = 1

Put y=1 into equation 3 and solve for x.

x = 4 + 3( 1) = 7

The correct ordered pair is (7,1)

If the level of significance of a hypothesis test is raised from 0.005 to 0.2, the probability of a type ii error will:_________
LiRa [457]

The probability of type II error will decrease if the level of significance of a hypothesis test is raised from 0.005 to 0.2.

<h3 /><h3>What is a type II error?</h3>

A type II error occurs when a false null hypothesis is not rejected or a true alternative hypothesis is mistakenly rejected.

It is denoted by 'β'. The power of the hypothesis is given by '1 - β'.

<h3>How the type II error is related to the significance level?</h3>

The relation between type II error and the significance level(α):

  • The higher values of significance level make it easier to reject the null hypothesis. So, the probability of type II error decreases.
  • The lower values of significance level make it fail to reject a false null hypothesis. So, the probability of type II error increases.
  • Thus, if the significance level increases, the type II error decreases and vice-versa.

From this, it is known that when the significance level of the given hypothesis test is raised from 0.005 to 0.2, the probability of type II error will decrease.
