A researcher surveyed 150 high school students and found that 68% played a musical insturment. What would be a reasonable range for the population mean?

The reasonable range for the population mean is (61%, 75%).

Step-by-step explanation:

The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.

The mean of the sampling distribution of sample proportion is, .

One of the best interval estimate of population proportion is the 95% confidence interval for proportion,

Given:

n = 150

= 0.68

The critical value of z for 95% confidence level is:

Compute the 95% confidence interval for proportion as follows:

Thus, the reasonable range for the population mean is (61%, 75%).

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
