Answer:
might be that the number across the ether side were the letter is might be order so(might be wrong tho
A) y, x, z
Step-by-step explanation:
A. 0.8 that’s the answer because if you divide 32 by 40 you get 0.8
Answer:
a.
H₀:β=0
H₁:β≠0
b.
p-value: 0.2935
95% CI: [-45.91;19.71]
Step-by-step explanation:
Hello!
You need to make a linear regression test. For this, you have two variables
X: Operators
Y: Wait time
x: 4 ; 5; 6; 7 ; 8
y: 385 ; 335 ; 383 ; 344 ; 288
The linear regression equation:
Yi: α + βxi + εi
a. The Hypothesis for a two-tailed test for the slope is:
H₀:β=0
H₁:β≠0
b.
The statistic is
t= (b-β)/√Sb₂ ~
I've used a statistic software to calculate the values
b= 10.31
= -1.27
p-value= 0.2935
The 95% CI for the slope, using the formula:
b±*Sb
is,
[-45.91;19.71]
I hope you have a SUPER day!
Answer:
18 tons
Step-by-step explanation:
a) Given: Weight of 1 truck=4500 pounds
Thus, weight of 8 trucks= pounds
We know that 1 ton=2000 pounds
Thus, weight of 8 trucks in tons=
Hence, the total weight in tons the cars on the truck= 18 tons.
b) Given: Dimensions of the room are as
Length=10 yards and width= 168 inches
We know that 1 yard=3 feet and 1 inch=
Thus, length
width=
The difference between length and width=
Hence, the length of the room exceed the width by 16 feet.
