A vision insurance company selects a SRS of 300 clients who wear contact lenses. They randomly assign 200 clients to the experimental group to receive an app that promotes contact lens hygiene. The remaining 100 clients form the control group. Suppose that without the app, 96%, percent of their clients with contact lenses would have healthy eyes for the year, and that with the app, 99%, percent would have healthy eyes.
After a year, the insurance company looks at the difference (Experimental−Control) between the proportions of clients with healthy eyes in each group.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
A
Approximately normal, because we expect 288 healthy and 12 not-healthy in both groups, and all of these counts are at least 10.
B
Approximately normal, because we expect 192 healthy and 20 not-healthy eyes for the experimental group, and 96 and 40 for the control group, and all of these counts are at least 10.
C
Not normal, because we expect fewer than 10 clients with healthy eyes in both groups.
D
Not normal, because we expect fewer than 10 clients with not-healthy eyes in both groups.
Answer:
NO, its D: Not normal, because we expect fewer than 101010 clients with not-healthy eyes in both groups.

A Right Cylinder has a radius of 3 cm and a height of 5 cm.
a. Find the Surface Area and Volume of the Right Cylinder.
Answer (Show Work):
b. If you wanted more volume in your cylinder, which of these two ideas would give the most Volume:
i. Doubling the radius to 6 cm, while the height remains 5 cm
OR
ii. Tripling the height to 15 inches, while the radius remains 3cm
Answer (Show Work):
Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
i. Doubling the radius to 6 cm, while the height remains 5
Step-by-step explanation:
Given that :
Radius, r = 3cm
Height, h = 5cm
Volume , V of right cylinder :
V = πr²h
V = π * 3² * 5
V = 141.37166
V = 141.37 cm³
Surface Area :
2πr(h + r)
2 * π * 3(3 +5)
18.849555(8)
150.79644
= 150.80 cm²
Volume at r = 6 ; h = 5
V = π * 6² * 5
V = 565.48667 cm³
Volume at r = 3 ; h = 15
V = π * 3² * 15
V = 424.11500 cm³
To increase volume,

Answer:
x= 1.25 y = 1.75
Step-by-step explanation:
8/5 = 10/ (5+x)
Cross multiplucation
8(5+x) = 5x10
40 + 8x = 50
8x = 10
x = 1.25
8/7 = 10/ (7+y)
Cross multiplication
8(7+y) = 10x7
56+8y = 70
8y = 14
y = 1.75

What is the sum of angles of quadrilateral?The sum of the angles of the quadrilateral is 360 degrees.
We need to find the ∠BCA:
∠OBD = 90
∠OAD = 90
So angles in quadrilateral BOAD
56, 90, 90 and∠ BOA
56 + 90 + 90 + ∠BOA = 360
∠BOA = 360 - 90 -90 - 56
∠BOA = 124
∠BCA is angle at circumference
∠BOA = 124, is the angle at centre
Angle at Centre = 2 x Angle at circumference
Angle at Circumference = Angle at Centre / 2 = 124/2 = 62
∠BCA = 62 degrees
thus, Option B. is correct.

Percentage (P) = [Final value - Initial value] / Initial value x 100
Diane makes fruit punch with 3 cups of cranberry juice, 2 cups of mandarin orange juice, and 3 cups of watermelon juice.
The percentage of the punch in cranberry juice will be given as,
P = [3 / (3 + 3 + 2)] x 100
P = (3 / 8) x 100
P = 0.375 x 100
P = 37.50%
