Question

It is believed that nearsightedness affects about 8% of all children. In a random sample of 194 children, 21 are nearsighted.

(a) Construct hypotheses appropriate for the following question: do these data provide evidence that the 8% value is inaccurate?

see attachment

(b) What proportion of children in this sample are nearsighted?
|(round to four decimal places)
(c) Given that the standard error of the sample proportion is 0.0195 and the point estimate follows a nearly
normal distribution, calculate the test statistic (use the Z-statistic).
Z =
(please round to two decimal places)
(d) What is the p-value for this hypothesis test?
p =
(please round to four decimal places)
(e) What is the conclusion of the hypothesis test?
Since p 2 a we accept the null hypothesis
Since p<a we reject the null hypothesis and accept the alternative
Since p 2 a we do not have enough evidence to reject the null hypothesis
Since p<a we fail to reject the null hypothesis
O Since p 2 a we reject the null hypothesis and accept the alternative
