For this one, use the order of operations to solve it, we called it PERMDAS to remember the steps.
14-6.2 times (-3+ -7)
So do the parenthesis first
-3+-7= -10
now the multiplication
-6.2 times -10= 62
a negative times a negative equal a 62
Now your problem is 14-62
Which equals -48.
So if I did my math and operations correctly, the answer would be B. -48.
Hope this helps!
<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>
