Answer:
The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022
Step-by-step explanation:
Upper Limit for 95% Confidence Interval can be calculated using p+ME where
- p is the sample proportion of defective gaming systems (
)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the statistic of 95% confidence level (1.96)
- p is the sample proportion (
- N is the sample size (1200)
Using the numbers we get:
ME=
≈ 0.007
Then upper limit for the population proportion is 0.015+0.007 =0.022

Answer:
Width = 25
Length = 25
Area = 625
Step-by-step explanation:
The perimeter of a rectangle is given by the sum of its four sides (2L+2W) while the area is given by the product of the its length by its width (LW). It is possible to write the area as a function of width as follows:
The value of W for which the derivate of the area function is zero is the width that yields the maximum area:
With the value of the width, the length (L) and the area (A) can be also be found:
Since the values satisfy the condition W≤L, the answer is:
Width = 25
Length = 25
Area = 625
