Question

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is? performed, how should you interpret a decision that? (a) rejects the null hypothesis or? (b) fails to reject the null? hypothesis? A scientist claims that the mean incubation period for the eggs of a species of bird is less than 35 days.

Answer 1

A scientist claims that the mean incubation period for the eggs of a species of bird is less than 35 days

Let x be the mean incubation period

Null Hypothesis H0: x>=35

Alternative Hypothesis HA: x<35

We perform the hypothesis test and find out the value of p and ?

p is calculated by finding P(X>X1) and P(X<-X1) where X1 is the test statistic value

If p<? reject null and if p>? then do not reject null
