Answer:
Option a) Compare the level of significance to the confidence coefficient.
Step-by-step explanation:
We are given the following information in the question:
We are performing a two-tailed test hypothesis. We can follow the following approaches:
Option a) Compare the level of significance to the confidence coefficient.
This cannot be used to perform hypothesis.
Option b) Compare the value of the test statistic to the critical value.
If the test statistic lies in the acceptance region evaluated by the critical value, we accept the null hypothesis. If not, we reject the null hypothesis.
Option c) Compare the confidence interval estimate of μ to the hypothesized value of μ.
If the estimated population lies in the calculated confidence interval, we accept the null hypothesis otherwise, we reject the null hypothesis.
Option d) Compare the p-value to the value of α.
If the p-value is greater than the significance level, we accept the null hypothesis. If it is lower than the significance level, we reject the null hypothesis.
Median is the central tendency of the data and always exists in the middle of the data set.
<h3>What is the median?</h3>
The Median is the middlemost value of the numbers arranged in the ascending orders. Median is the central tendency of the data and always exists in the middle of the data set.
The process of finding the median if the number of data points is even is as follows:
- Put the numbers or the data points in the order(increasing or decreasing i.e. ascending or descending order)
- Next cross of the high/ low pairs
- Add the leftover numbers
- and divide the number( as obtained in the above step by 2)
( if the number of data pints were even then we just need to arrange the numbers and cross the high/low pair and only one data point will be left which acts as the Median of the data set)

There isn’t a picture so we can see
Answer:
4.5>2.89
Step-by-step explanation:
This question is asking for the comparison between the values of both numbers. 4.5 is greater than 2.89, and this can be written as 4.5>2.89
ANSWER IS 5
so
how many years ago=x
so
'in how many years ago (-x) was ethan 5 times older than son
40-x means ethan's age x years ago
12-x means son's age x years ago
so
ethan's age x years ago is 5 times as much as son's age 5 years ago
40-x=5(12-x)
distribute using a(b+c)=ab+ac
40-x=60-5x
add 5x
40+4x=60
subtract 40
4x=20
divide 4
x=5
ANSWER IS 5 years
