Answer:
± 1.96 and the same as for a two-tailed z test at a 0.05 level of significance.
Step-by-step explanation:
We are given the following information in the question:
We perform a two-tailed hypothesis at a 0.05 level of significance.
We have to state the critical values for the same.
Z-critical:
T-critical:
The critical value for t depends upon the degree of freedom which is obtained from the sample size.
If n is the sample size, then , n - 1 is the degree of freedom.
which is the same as the z-critical
The formula for an equation is y=mx+b. M is the slope and B is the y-intercept. Since the slope is -1 and the y-intercept is -6 the equation would be y=-1x-6
600sqrt3 which equals 1039 inches
A Yes as the x values are all different
B f(x) = 5x + 14
when x = 2 , f(x) = 5(2) + 14 = 24
x = 5, f(x) = 39,
Each value of f(x) is greater than corresponding ones in the function in A.
when x = 9 f(x) = 59 which is greater than for first function ( =12)
First function is a decreasing while f(x) is increasing
C f(x) = 64 = 5x + 14
5x = 64 - 14 = 50
x = 10
