Answer:
Step-by-step explanation:
From the information given,
The null hypothesis is
H0:p = 0.40 H0:p = 0.40
The alternative hypothesis
Ha:p < 0.40 Ha:p < 0.40.
The p value of 0.033
The decision rule states that
If the significance level, α < the p value, we would accept the null hypothesis.
If the significance level, α > the p value, we would reject the null hypothesis.
From the given options,
D) At the significance level α=0.05, the null hypothesis is rejected. There is convincing evidence to support the claim that fewer than 40% of the students at the local university read at least one book last year.
The correct answer is <span>y = 5/13. We say this due to the next procedure:
</span>cos^2 + sin^2 = 1
(-12/13)^2 + sin^2 = 1
144/169 + sin^2 = 1
sin^2 = 1-144/169
sin^2 = 25/169
sin = sqrt(25/169)
sin = 5/13
Hope this can help you greatly
