Answer:
Step-by-step explanation:
(a)
The sample statistic which is estimated by the population parameter is the sample mean. Moreover it is the best estimate for the population mean.From the information, it is clear that
The sample mean is the best point estimate for the population mean. This clearly indicates that the best point estimate for the population mean is 5.1mg/dl.
(b)
From the information, it is clear that
The degree of freedom is obtained below:
From “Student’s-t Distribution Table”, the required critical value is 2.704 which is lesser than the critical value.
The 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment is,
(c)
From the information, it is clear that the cholesterol levels were measured and identified whether the garlic treatment affects the LDL cholesterol levels or not.
It is clear that, the 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment is . By the rejection rule for the confidence interval it is clear that the confidence interval contains 0 which clearly states that the garlic treatments do affect the LDL cholesterol levels.

Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
The two angles are alternate interior angles. If they lines are parallel, then the angles are equal.
7x-7 = 4x+14
Subtract 4x from each side
7x-4x -7 = 4x-4x+14
3x-7 = 14
Add 7 to each side
3x-7+7 = 14+7
3x=21
Divide by 3
3x/3 =21/3
x=7
The right answer is Option B: f(4) = 38
Step-by-step explanation:
Given function is;
For finding f(4), we will put x=4 in the given function; therefore
Putting x=4 in given function,
Therefore;
f(4) = 38 in the given function.
The right answer is Option B: f(4) = 38

Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
