Answer:

Type I error: Concluded that p ≠ 11% when it is 11%.

Type II error: Concluded that p = 11% when it is not 11%.

Step-by-step explanation:

A <em>type I error</em> is the rejection of the null hypothesis (<em>H₀</em>) when indeed the null hypothesis is true. It is symbolized by <em>α</em>.

A <em>type II error</em> is failing to discard the null hypothesis when indeed the null hypothesis is false. It is symbolized by <em>β</em>.

In this case a  principal of a school claims that the percentage of students at his school that come from single-parent homes is 11%.

The hypothesis to test this claim is:

<em>H₀</em>: The proportion of students at the school that come from single-parent homes is 11%, i.e. <em>p</em> = 0.11.

<em>Hₐ</em>: The proportion of students at the school that come from single-parent homes is not 11%, i.e. <em>p</em> ≠ 0.11.

  • The type I error will be committed when it is concluded that the proportion of students at the school that come from single-parent homes is not 11% when in fact it is 11%.
  • The type II error will be committed when it is concluded that the proportion of students at the school that come from single-parent homes is 11% when it is not.

One side of a square is 11 ft. Tom found that the area of his square is 22. Is Tom correct? Explain why he is correct or incorre
guapka [62]

Answer:

Tom is incorrect.

Step-by-step explanation:

A square by definition implies that all sides of the square are the same measurements. In the case of finding the area, A = s². Tom, however, solved it as A = 2s.

In this case:

Area of square = s² = 11² = 121 ft²

121 ft² is the correct measurement.
