Question

Are the following statements H0: u > equal to 4; HA: U < equal to 17 a valid pair of null and alternative hypothesis?

A,) No, these statements both compare a parameter to a value

B.) No, there are no parameters contained in these statements

C.) No, the alternative hypothesis cannot contain numeric values

D.)No, the null hypothesis uses an inequality to compare the paramete to a value

Answer 1

A hypothesis test formally tests if a population parameter is equal to a hypothesized value.

The null hypothesis states that the parameter is equal to the hypothesized value, against the alternative hypothesis that it is not equal to (or less than, or greater than) the hypothesized value. When the test p-value is small, you can reject the null hypothesis and conclude the sample is not from a population with the parameter equal to the hypothesized value.

Alternate hypothesis cant contain equal to sign.

B.) No, there are no parameters contained in these statements
