Answer:
The null hypothesis is 
The alternate hypothesis is 
Step-by-step explanation:
To investigate this further, the economist would like to test the claim that the percent of thirty-year fixed-rate mortgage loans that have a 4.75 percent interest rate is less than 22%.
At the null hypothesis, we test that the proportion is of 22%, that is:

At the alternate hypothesis, we test that the proportion is less than 22%, that is:

The volume of the cylinder is 4710 cubic inches
Step-by-step explanation:
Volume of the cone = 1570 cubic inches
Volume of cone = 1/3(volume of the cylinder)
So,
Volume of the cylinder = 3(volume of the cone)
Volume of the cylinder = 3(1570)
= 4710 cubic inches
The volume of the cylinder is 4710 cubic inches
I think it’s the last one
60 is what percent of 200...
60/200 = x/100
200x = 6000
x = 6000/200
x = 30%...that means for every sale, the sales person gets a 30% commission
C(p) = 0.3p <==
Answer: 1,356 tickets
12x=16,272
divide by 12 on both sides
12x÷12=16,272÷12
x=16,272÷12
x=1,356
I hope this is good enough:
