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=

A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ , of the population from which the sample was drawn. Use the P-value approach. Also, assess the strength of the evidence against the null hypothesis. sample mean = 24.4, s = 9.2, n=25, H0: μ = 26, Ha : μ , 26, α = 0.05 Options: A: Test statistic: t = -0.87. P-value = 0.1922....
