Answer:
a. Yes
See explanation below.
Step-by-step explanation:
Assuming that if the question is if we can use the normal approximation for the true proportion.
For this case we have n = 40 and p = 0.3 (probability of success)
We need to check some conditions:
1) Random sample : This condition is satisfied since the problem says that she randomly select 40 records
2) 
3) 10% condition: the random sample is assumed to be less than 10% of the original population size (assumed)
The population proportion have the following distribution
So then as we can see the normal approximation for this case makes sense since we have all the 3 conditions satisfied so then the answer would be:
a. Yes
Answer:
b)
Circumference Formula :
This is the ratio we can work out:

Answer: 3.5</h3>
=========================================
Explanation:
Start by sorting the values from smallest to largest. This is known as ascending order. The original set {3, 5, 7, 4, 3, 1} will sort to {1, 3, 3, 4, 5, 7}
After the values are sorted, we will look at the middle most value to find the median. Because there are six items in this data set, the median number is between slot 3 and slot 4. Note how the sorted data set breaks down into
{1, 3, 3} and {4, 5, 7}
we see that 3 and 4 are tied for the middle most, so the median must be 3.5 which is halfway between 3 and 4.
The distance between ladder and bottom of the slide is 4.9 meters.
Step-by-step explanation:
Given,
Height of ladder = 1 m
Length of slide = 5 m
The ladder will serve as perpendicular and slide will serve as hypotenuse.
The distance from bottom of the slide to ladder will be base.
a = 1
c = 5
Taking square root on both sides
Rounding to the nearest tenth
b = 4.9 meters
The distance between ladder and bottom of the slide is 4.9 meters.
