Question

Find the pvalue based on a standard normal distribution for each of the following standardized test statistics.
HELP!! I need the pvalue for all three questions. If you could provide a brief explanation on how you got that, that would be much appreciated (: Chapter 5, Section 1, Exercise 013 Find the p-value based on a standard normal distribution for each of the following standardized test statistics. (a) Z = 0.76 for a right tail test for a difference in two proportions Round your answer to two decimal places. p-value= the tolerance is +/-9% (b) Z =-2.38 for a left tail test for a difference in two means Round your answer to three decimal places. p-value= the tolerance is +/-9% | (c) Z = 2.31 for a two-tailed test for a proportion Round your answer to three decimal places

Explanation / Answer

a) 22.36 %

b)0.866 %

c)2.088%

The above values have been calculated using a normal z table, where we see the value and then the corresponding percentage of area that is described. For a right or left tailed test, we simply pick the percentage but for two-tailed test, we multiply it by 2.
