Approximately 9.4
Hope this helps :)
What are you looking for? The X? Tell us exactly.
<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
I don’t speak Spanish but if you put the English trans in the comments I’d love to answer
