6 0

Well I’ll just make my own table
Key/legend: when y = 0 x = -2
X=|-3 |-2 | -1| 0|1 |2|3 |4 |5 |
Y=|17 |-12|-7|-2|3|8|13|18|23|

ANSWER THIS!!!!!!!!!!

cluponka [151]

Answer:

r = sqrt( 3V/( pih))

Step-by-step explanation:

V = 1/3 pi r^2 h

Solving for r

Multiply each side by 3

3V = pi r^2h

Divide each side by pi h

3V/( pi h) = r^2

Take the square root of each side

sqrt( 3V/ (pi h) )= sqrt( r^2)

sqrt( 3V/ (pi h)) = r

A researcher reports survey results by stating that the standard error of the mean is 25 the population standard deviation is 40

Answer:

a) A sample of 256 was used in this survey.

b) 45.14% probability that the point estimate was within ±15 of the population mean

Step-by-step explanation:

This question is solved using the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
