Answer:
The value of the test statistic is 
Step-by-step explanation:
The test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
Test if the mean is equal to 5:
This means that the null hypothesis is 
A simple random sample of wrist breadths of 40 women has a mean of 5.07 cm. The population standard deviation is 0.33 cm.
This means that 
Find the value of the test statistic?



The value of the test statistic is 
Answer:
what do i have to answer?
Step-by-step explanation:
The limit for the given piecewise function does not exist(DNE).
4th option is correct.
<h3 /><h3>What is the limit of a function?</h3>
In mathematics, limits are the points at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend heavily on limits, which are required to determine integrals, derivatives, and continuity. It is applied during the analysis process and always focuses on the function's behavior at a certain time.
Unique real numbers are limits in mathematics.
According to the question,
Left hand limit of the function= -5(3)+4 = -15+4 = -11
Right hand limit of the function= (3)(3)+2 = 11
As the left and right-hand limits are not equal. Thus, the limit of the function does not exist.

2(-2x+4)= -6x+12. ---> -4x+8= -6x+12 ---> combine like terms so +4x to -6x to get 8= -2x+12 ---> -12 on both sides to get -4= -2x --> divide both sides by -2 to get 2= x
