34x - 136 = 9
(34x - 136) + 136 = 9 + 13634x = 14534x / 34 = 145 / 34x = 4.26470588235x = 4.26 (2 dp.)
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%).
Answer:
3 gallons of orange juice
To solve this problem, we simply have to multiply the
original inches of rain to that of how many times it was for the rest of
summer. So in this case, simply multiply 2.29 by 3, that is:
2.29 inches * 3 = 6.87 inches
