Wall thickness of 25 glass 2-liter bottles was measured by a quality-control engineer. The sample mean was and the sample standard deviation is Compute 90% lower tolerance bound on bottle wall thickness that has confidence level 90%. Assume population is approximately normally distributed. Assume tolerance factor is 1.702. Round your answer to 2 decimal places.

1.7

Step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
