Answer:
The correct option is (i) I expect the confidence interval based on the sample of 64 data values to be more precise.
Step-by-step explanation:
Consider the provided information.
The sample size is inversely proportional to the standard error of the sample mean decreases. 
As the size increase the standard error of the sample mean decreases.
Hence, for greater precision select the confidence interval based on the greater sample of data.
Therefore, we expect the confidence interval based on the sample of 64 data values to be more precise.
The correct option is (i) I expect the confidence interval based on the sample of 64 data values to be more precise.
Answer:
Step-by-step explanation:
Looking at the right angle triangle that contains x and y, we would apply trigonometric ratio to determine x an y. Taking 60 degrees as the reference angle,
Hypotenuse = y
Adjacent side = x
Opposite side = 36
Therefore,
Sin # = opposite side / hypotenuse
Sin 60 = 36/y
y = 36/Sin60 = 36/0.8660 = 41.57
Cos # = adjacent side/hypotenuse
Cos 60 = x/41.57
x = 41.57Cos 60 = 41.57 × 0.5 = 20.785
Sin45 = z/36
z = 36Sin45 = 36 × 0.7071 = 25.4556
The answer for this question is c-32,760.00
