Overview
Q1:You are given the following hypothesis test:
H0: μ=100
H1: μ ≠ 100
The calculated test statistic z = –1.0, and the critical value of z = ±1.97. Then, the decision would be to:
Reject H0 since z < –1.97 | ||
Reject H0 since –1.97 < z < 1.97 | ||
Fail to reject H0 since z < –1.97 | ||
Fail to reject H0 since –1.97 < z < 1.97 |
Q2: With 0.05 significance level, H1: p > 0.5, and the value of test statistics is z = 1.86, then the P-value is equal to?
Q3: The null hypothesis and the alternative hypothesis for the following claim: “Maruti motor company claims that its new SUV, the Vista II, will average more than 40 miles per gallon in the city” are:
H0 : µ > 40, H1: µ ≤ 40 | ||
H0 : µ = 40, H1: µ > 40 | ||
H0 : µ < 40, H1: µ ≥ 40 | ||
H0 : µ = 40, H1: µ < 40 |
