Answer:
Step-by-step explanation:
Every integer is a rational number.
Answer:
Given:
n = 1003
q = 1 - 0.4606 = 0.5394
a) The sample size and count.
Here the sample size is the number that took part in the poll. It is denoted as n = 1003.
The count is the number that answered yes. Count = 462
b) The sample proportion.
The formula for sample proportion is:
Therefore, sample proportion =
c) The relationship between population proportion and sample proportion.
Since the sample size is greater than 30 (n>30), the sample size is large. Hence, for a large sample, the population proportion is approximately equal to the sample proportion.
This means the population proportion, p = 0.4606
Note that a percentile tells us how many percents of numbers that are above the number at the percentile. So the 70th percentile tells us that 70% of the students are taller than Jake. That means 30% of the students are either at the same height or shorter than Jake.
30% of 1100 would be 0.3*1100 = 330.
So there are 330 students that are either at the same height or shorter than Jake.
The formula of a slope:
We have the points (4, 1) and (2, 5). Substitute:
<h3>Answer: The slope is -2.</h3>
