The T-test or T statistical test should be performed to test the given hypothesis: verage time to deliver pizza, once the order is placed, is greater than 25 minutes in the population.
As we know that, a statistical test called a t-test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment truly affects the population of interest or whether two groups differ from one another.
The three t-test used to compare means are the one-sample, two-sample, and paired t-tests. By using the formula
t = (m - μ) / (s/√n)
Where,
t = t-test
m = mean
m - μ = theoretical value
s = standard deviation
n = variable set size

First no. = x
Second no. = y
Equation Formation
x = 2 y + 4
x + y = 10
2 y + 4 +y = 10
3 y = 6
y = 2
x = 4 + 4
x =8
Answer = 2 , 8
Answer:
3 inches
Step-by-step explanation:
Lenght = 18 inches
Width =15 inches
Perimeter of the rectangular painting and frame = 90 inches
Let X be the width of the frame
The width of the framed picture = 15 + 2x
The length of the framed picture = 18 + 2x
Perimeter = 2 (L + W)
90 = 2(15 + 2x + 18+ 2x)
90 = 2(33 + 4x)
90 = 66 + 8x
8x = 90 - 66
8x = 24
x = 24/8
x = 3 inches
the width of the frame is 3 inches
