Answer:
You'll be fine.
Step-by-step explanation:
Answer:
Explained below.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
A random sample of <em>n</em> = 658 items is sampled randomly from this population.
As the sample size is large, i.e. <em>n</em> = 658 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.
Compute the mean and standard deviation as follows:
(a)
Compute the probability that the sample proportion is greater than 0.63 as follows:
(b)
Compute the probability that the sample proportion is between 0.60 and 0.66 as follows:
(c)
Compute the probability that the sample proportion is greater than 0.592 as follows:
(d)
Compute the probability that the sample proportion is between 0.57 and 0.60 as follows:
(e)
Compute the probability that the sample proportion is less than 0.51 as follows:
For the first part you need to find 85% of 16,000. its 13,600. you get this by multiplying .85 by 16,000.
for part two, i don't know how to show the work, but 816 is 96% of 850.
sorry about that, but i hope it helps
Answer:
y = -3/2x + 2
Step-by-step explanation:
<u>Step 1: Use point slope form to find the equation</u>
(y - y1) = m(x - x1)
(y - (-7)) = -3/2(x - 6)
y + 7 - 7 = -3/2x + 9 - 7
<em>y = -3/2x + 2</em>
<em />
Answer: y = -3/2x + 2
WHAT DOES THIS MEAN? I’m confused
