Answer: 10
Step-by-step explanation: 10 divided by 5 is 2. 2 times 2 is 4
Answer:
144*
Step-by-step explanation:
decagon has 10 sides every side is 144* angles
Answer:
We accept the null hypothesis and reject the alternate hypothesis. There is no evidence to conclude that the population mean is greater than 29. The population mean is less than or equal to 29.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 29
Sample mean,
= 30
Sample size, n = 47
Alpha, α = 0.05
Population standard deviation, σ = 5
First, we design the null and the alternate hypothesis
a) This is a one-tailed test because the alternate hypothesis is in greater than direction.
We use One-tailed z test to perform this hypothesis.
b)
, we reject the null hypothesis and accept the alternate hypothesis and if
, we accept the null hypothesis and reject the alternate hypothesis.
c) Formula:
Putting all the values, we have
d) Now,
Since,
We accept the null hypothesis and reject the alternate hypothesis. There is no evidence to conclude that the population mean is greater than 29. The population mean is less than or equal to 29.
e) P-value is 0.0853
On the basis of p value we again accept the null hypothesis.
Let
x= total cost of cars
y= total commission paid out for all cars sold
6%= 6/100 = .06
Set up an equation:
y= .06(x)
Given: x= $125,650
substitute into the y= .06(x)
multiply $125,650 by .06.
The answers would be: 7539
hope this helped :)
