Answer:
from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05
Step-by-step explanation:
Given that;
= 6.5 gpm
μ = 5 gpm
n = eight runs = 8
standard deviation σ = 1.9 gpm
Test statistics;
t = ( - μ) /
we substitute
t = (6.5 - 5) /
t = 1.5 / 0.67175
t = 2.23
the degree of freedom df = n-1 = 8 - 1
df = 7
Now, from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05

Answer: I think 48 degrees
Step-by-step explanation: they are both diagonal
hope this helps, have a great day!! :D
2x + y = 4
2x - y = 8
-------------add
4x = 12
x = 12/4
x = 3
2x + y = 4
2(3) + y = 4
6 + y = 4
y = 4 - 6
y = -2
okay....so x = 3 and y = -2
3x - y = ?
3(3) - (-2) = ?
9 + 2 = 11....so ur answer is 11
