Answer:

the probability of a Type I error is 0.10

Explanation:

Given the data in the question;

significance level ∝ = 0.10

Null H₀ hypothesis is true;

the probability of a Type I error = ?

we know that; a type 1 error is the error of rejecting a Null hypothesis when in reality, it is true. That is false positive.

Hence, our type 1 error will be;

P(rejecting null | null true ) = significance level ∝ = 0.10

Therefore, the probability of a Type I error is 0.10
