Step-by-step explanation:
Mean = 
The manufacturer does not want to replace more than 5% of the tires
By using normal table values :
Hence the approximate number of miles for the warranty is 42580 miles

Answer:
(0.30, 0.42)
Step-by-step explanation:
Given the sample proportion is = 0.36
Number of trials required for determining the margin of the error = 100
Sample size, n = 50
The point estimate = 0.36
The minimum sample proportion form the simulation = 0.28
The maximum sample proportion from the simulation = 0.40
Also the margin of the error of population proportion is found by using the half of the range.
Therefore, the interval estimate for the true population proportion is = (0.30, 0.42)
Answer:
x = 675
Step-by-step explanation:
Collect terms and solve the resulting 2-step linear equation.
(x-355)+(x)+(80+2x)=2425 . . . . . given
4x -275 = 2425 . . . simplify
4x = 2700 . . . . . . . add 275
x = 675 . . . . . . . . . divide by 4
