Is this significant evidence to conclude that the proportion of infants who receive Prevnar and experience a loss of appetite is different than 0.135 which is the proportion of children who experience a loss of appetite with competing medications? is an a of .05.
a) state the null and alternative hypotheses.
b) calculate the test statistic.
c)report the p-value
d)state a conclusion in context of the problem.
e)calculate a 95% confidence interval for the proportion of infants on Preener who experience a loss of appetite. Interpret the confidence interval in context of the problem.
f) does your confidence interval agree with the results of the hypothesis test? explain.
