Hello!
The objective is to compare the mean rating on the client satisfaction survey of two consultants A and B.
Consultant A
X₁: Rating on the client satisfaction survey given to consultant A
n₁= 16
X[bar]₁= 6.82
S₁= 0.64
Consultant B
X₂: Rating on the client satisfaction survey given to consultant B
n₂= 10
X[bar]₂= 6.25
S₂= 0.75
a. The claim is that consultant A, which is more experienced, has a higher average service rate than consultant B, which has less experience, then the hypotheses are:
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂
b. If both variables have a normal distribution and the population's variances are unknown but equal, the statistic for this test is a t-test for independent samples with pooled sample variance.
Sa= 0.68
c. The p-value is the probability of obtaining a value as extreme as the value of the statistic. As the test it is one-tailed and has the same direction (right), symbolically:
P(t₂₄≥2.079)= 1 - P(t₂₄<2.079)= 1 - 0.9758= 0.0242
d. The p-value:0.0242 is less than α:0.05, then the decision is to reject the null hypothesis.
Using a significance level of 5%, there is significant evidence to say that the average service rate of consultant A is higher than the average service rate of consultant B.
I hope this helps!
Answer:

Step-by-step explanation:
your welccome
So just basically calculate the area of the green thing. you can split it in 2 section. one is the long rectangle on top and other is the smaller rectangle.
area= 11x3 + 3x2
= 33+ 6
=39
so we need 39 squera ft of carpet
Answer:
y=9/5x+5
Step-by-step explanation:
y-(-4)/x-(-5)=9/5
y+4/x+5=9/5
5(y+4)=9(x+5)
5y+20=9x+45 , 5y=9x+45-20
5y=9x+25
y=9x+25/5=9/5x +5
