2/5, %52, 0.57
0.57 is 57 percent, being the highest fraction.
2/5 of a percentage is 40 percent.
52 percent is in it's percentage form, so it does not have to be changed.

While the goal of hypothesis testing is to test a claim, the goal of estimation is to estimate a

ella [17]

The estimation goal is to estimate a population parameter. The estimation process uses sample statistics.

<h3>What is the goal of hypothesis testing?</h3>

The goal of hypothesis testing is testing to claim whether it is right or wrong.

The hypothesis testing also uses statistics to determine whether or not a treatment has an effect.

<h3>What is the goal of estimation?</h3>

The estimation goal is to estimate a population parameter. The estimation is used to determine how much effect a treatment has.

To estimate a parameter, a sample statistics of the parameter is used.

Thus, the estimation is to estimate a population parameter.

The points obtained by students of a class in a test are normally distributed with a mean of 60 points and a standard deviation

Paraphin [41]

Answer:

0.13% of students have scored less than 45 points

Step-by-step explanation:

Problems of normally distributed samples can be solved using 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.

In this problem, we have that:

$\mu = 60, \sigma = 5$

About what percent of students have scored less than 45 points?

This is the pvalue of Z when X = 45. So

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

$Z = \frac{45 - 60}{5}$

$Z = -3$

$Z = -3$ has a pvalue of 0.0013

0.13% of students have scored less than 45 points

1) Which two teams had the greatest point difference?

MrMuchimi

1) Which two teams had the greatest point difference?
Delta and Beta (85 - 25 = 60)

2) Which two teams had the least point difference?
Delta and Gamma (85 - 75 = 10)

3) What was the average score of the 5 teams?
(45+25+75+85+65) / 5 = 295 / 5 = 59

4) How many more points did Epsilon score than Beta?
Epsilon: 65
Beta: 25
65 - 25 = 40
Epsilon scored 40 more than Beta

5) Which teams scored more than 2 times Beta’s score?
twice of Beta = 25 x 2 = 50

answer
Gamma (75) , Delta (85) and Epsilon (65)

If 2 sides of a triangle measure 6 and 16 find the range for the 3rd side

tangare [24]

Step-by-step explanation:

Range if third side is in between 10-22

Reason:

For the lowest value of third side 16-6= 10

For the highest value if third side 16+6= 22
