Question 754009
Give the value of the test statistic t in each of the following situations. (Round your answers to two decimal places.)
H0: μ = 40, x¯ = 70, s = 90, n = 100
t = {{{(70 - 40)/(90/sqrt(100))}}} = {{{highlight(3.33)}}}
Null value = 100, sample mean = 93, s = 15, sample size = 40
t= {{{(93 - 100)/(15/sqrt(40))}}} = {{{highlight(-2.95)}}}
H0: μ = 230, x¯ = 280, standard error = 5, n = 100
t= {{{(280 - 230)/5}}} = {{{highlight(10)}}}
