Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Answer:
It's not. b = 15p
Step-by-step explanation:
The <em>division property of equality</em> says you can divide both sides of an equation by the same number without changing the values of the variables. When we divide both sides of the given equation by 2, we get ...
2b/2 = 30p/2
b = 15p . . . . . . . simplify
Answer:
$1400
Step-by-step explanation:
Salary of a Sandy working as a Chef= $ 35000
Percentage of a salary spent on expenses= 4%
Amount of money spent on expenses= 4 % of $35000
Amount of money spent on expenses= $1400
Hence he spent $1400 on expenses
Hence, the correct answer is $1400
