Answer:
We accept the null hypothesis and conclude that voltage for these networks is 232 V.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 232 V
Sample mean,
= 231.5 V
Sample size, n = 66
Sample standard deviation, s = 2.19 V
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,

We accept the null hypothesis and conclude that voltage for these networks is 232 V.
Answer:
it's very simple..just see the image which I have sended you I have done it myself...hope you will understand

please do follow me and keep asking me questions of maths and science I am quite good in them and don't forget to mark me as the brainliest answer✌✌
A number is an arithmetic value that is used to represent a quantity and calculate it. The two numbers will be 17 and 0, so the product of the two is minimal.
<h3>What are Numbers?</h3>
A number is an arithmetic value that is used to represent a quantity and calculate it. Numericals are written symbols that represent numbers, such as "3."
Given the difference between the two numbers is 17. Let the first number be zero, then the second number will be 17. Thus, the product of the two numbers will be 0, which is the minimum.
If the first number is further increased such as 1, then the other number will be 18, and the product of the two will be 18, which is greater than zero.
Hence, the two numbers will be 17 and 0, so the product of the two is minimal.
