2. Consider the null hypothesis Ho:p = 0.18 indicates that the proportion of fat content of the
burgers being sold in the canteen is 18% or less. Which of the following is true about the type I and type
II error?
%3D
A. A type I error occurs when the actual proportion is about 18% or more, but the null
hypothesis is rejected. A type II error when the actual proportion is about18% or less but
the null hypothesis is rejected.
B. A type I error occurs when the actual proportion is about 18% or less, but the null
hypothesis is rejected. A type II error occurs when the actual proportion is about 18% or
more, but the null hypothesis is accepted.
C. Atype I error occurs when the actual proportion is about 18% or more, but the null
hypothesis is accepted. A type II error occurs when the actual proportion is about 18% o
less, but the null hypothesis is rejected.
D. Atype I error occurs when the actual proportion is about 18%, and the null hypothesis is
rejected. A type II error occurs when the actual proportion is about 18% or less, but the
null hypothesis is rejected.
