Total students he surveyed: 27
Amount that found it something OTHER than easy: 14 (11 moderate + 3 difficult)
This means that

Answer:
A) H1: π < 0.10
Step-by-step explanation:
<u>One tailed test</u>:-
A test of any statistical hypothesis where the alternative hypothesis is one tailed ( right tailed or left tailed) is called a one - tailed test.
H1: μ < μ0 (left tailed test)
H1: μ > μ0 (right tailed test)
<u>two tailed test</u>:-
In a test of statistical hypothesis where the alternative hypothesis is two tailed , we assume that the null hypothesis
H0: μ = μ0 against the alternative hypothesis
H1: μ ≠ μ0
conclusion:-
given data It is claimed that in a bushel of peaches, fewer than 10% are defective so alternative hypothesis
H1: μ < 0.10
