Answer:
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 <em>z</em> 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%).
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
The exponent or power of a number represent the multiplication of the that number to the power times.
Let suppose a number 2 has the power 2. Then it will be equal to,
Similarly, 3 times of number 2 equal to the number 2 with exponent 3.
The expression is m times, m times, m times, m times, m. It can be written as,
The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
