We have been given that the total number of households she surveyed = 150
Now, out of 150, 35 of them said they turn out the lights each year on Halloween.
Now, in order to find the percentage of households that turn out the lights each year on Halloween, we will divide 35 by 150 and then multiply the result with 10.
Thus, we the required percentage is given by
Therefore, to nearest percent is 23%.
Hence, the estimated population proportion of households that turn out the lights each year on Halloween is 23%
The sample mean is an estimate of the population mean.
The sample mean is exactly equal to the population mean
<h3>How to determine the true statement</h3>
When the population mean is known; the value of the population mean can be used as the sample mean.
This is so because:
The sample mean is an estimate of the population mean.
And it is represented as:
Hence, the true statement is that the sample mean is exactly equal to the population mean

Answer:
the answer is 918
Step-by-step explanation:
first you would see how many times 257 could go into 28 which is about 9 so you could do 9 times 28 which is 257-252 which is 5. Then bring the 7 down to make 57. Then repeat the first step with every time and you should get 918. (57 goes into 28 once)
Answer:
