Determine if the conditions required for the normal approximation to the binomial are met. If so, calculate the test statistic, determine the critical value(s), and use that to decide whether there is sufficient evidence to reject the null hypothesis or not at the given level of significance.

Hypotheses, the sample statistic, and the standard error are given. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Assume the sample size is large enough to use the standard normal distribution. Test H0 : p=0.35 vs Ha : p>0.35 when the sample has p^=0.41 and the standard error is SE=0.02. round to 3.dp test statistic= p-value=

Answer the following True or False: Suppose a sample size of 87 was used to conduct a right tailed hypothesis test for a single population mean. The null hypothesis was H0: μμ = 45 and the sample mean was 50 and the p-value was 0.03. Then there is a 3% chance that 87 randomly selected individuals from a population with a mean of 45 and the same standard deviation would have a sample mean greater than 50. false true
