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:
The cumulative frequency distribution that corresponds to the given frequency distribution is shown in the explanation part as well as in the attachment.
Step-by-step explanation:
A cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution.
The cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars is shown below and better shown in the attachment below.
Speed Number of cars Cumulative frequency
0 - 29 4 4
30 - 59 16 20
60 - 89 60 80
90 - 119 20 100
Answer:
C
Step-by-step explanation:
The probability of getting heads or tails is 50%.
300*50% = 150
