The critical value for a hypothesis test​ _______.

Mathematics
1 answer:
Jlenok [28]3 years ago
7 0

Answer:

Option C) Critical value is based on the significance level and determines the boundary for the rejection region

Step-by-step explanation:

Critical Value:

  • In hypothesis testing, a critical value is a point that is compared to the test statistic
  • It is used to determine whether to reject the null hypothesis or accept the null hypothesis.
  • If the absolute value of your test statistic is greater than the critical value,we fail to accept the null hypothesis and reject it.
  • Critical value is affected by the significance level of the testing.
  • It is the value that a test statistic must exceed in order for the the null hypothesis to be rejected.

Thus, option C) is the correct interpretation of critical values.

Option C) Critical value is based on the significance level and determines the boundary for the rejection region

3 |-3x + 9| = -18

/3 /3

|-3x + 9| = -6

-3x + 9 = -6 -3x + 9 = 6

-9 -9 -9 -9

-3x = -15 -3x = -3

/-3 /-3 /-3 /-3

A video game company is designing a game based on professional race cars. Professional race cars have a length of 570 cm and a w
siniylev [52]

Answer:

  A) 1/45

  B) 1/60

Step-by-step explanation:

<u>Part A</u>

The actual car has a length to width ratio of ...

  length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6

The rectangle on the screen has a length to width ratio of ...

  length/width = (13 cm)/(4 cm) = 3 1/4

Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.

For a model width of 4 cm, the scale factor is ...

  model/life-size = (4 cm)/(180 cm) = 1/45

__

<u>Part B</u>

For a model width of 3 cm, the scale factor is ...

  model/life-size = (3 cm)/(180 cm) = 1/60
