O False
Answers
Answer:
True
Step-by-step explanation:
The skip interval in systematic random sampling is computed by dividing the number of potential sampling units on the list by the desired sample size .
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval (the sampling interval).
Sampling interval is calculated by dividing the population size by the desired sample size

Vitamin D is needed for the body to use calcium. An experiment is designed the effects of calcium and vitamin D supplements on the bones of first-year college students. The outcome measure is the total body mineral content (TBBMC), a measure of bone health. Three doses of calcium wil be used: 0, 200, and 400 mg/day. The doses of vitamin D will be 0, 50, and 100 international units (IU) per day. The calcium and vitamin D will be given in a single tablet. Al tablets including those with no calcium and no vitamin D will look identical. Subjects for the study will be 90 men and 90 women.a) What are the factors and the treatments for this experiment?b) Draw a picture explaining how you would randomize the 180 college students to the treatmentsc) Use a spreadsheet to carry out the randomization

Sorry this is a really really late reply but to find the median on the graph you need to find the mid value, so for example if the y axis goes up to 60, then the middle of the values will be 30. You go across this 30th value and find the median.
Hope this helps.

Completed question:
An initial time study resulted in an average observed time of 2.2 minutes per cycle, and a standard deviation of .3 minutes per cycle. The performance rating was 1.20. What sample size, including the 20 observations in the initial study, would be necessary to have a confidence of 95.44 percent that the observed time was within 4 percent of the true value?
Answer:
47
Step-by-step explanation:
When doing a statistic study, a sample of the total amount must be taken. This sample must be done randomly, and, to be successful, the sample size (n) must be determined, by:
Where Z(α/2) is the value of the standard normal variable associated with the confidence, S is the standard deviation, and E is the precision. The confidence indicates if the study would have the same result if it would be done several times. For a confidence of 95.44, Z(α/2) = 2.
The standard deviation indicates how much of the products deviate from the ideal value, and the precision indicates how much the result can deviate from the ideal. So, if it may vary 4% of the true value (2.2), thus E = 0.04*2.2 = 0.088.
n = [(2*0.3)/0.088]²
n = 46.48
n = 47 observations.

The equation becomes 4610 = 2115, which is not true.
Let's break down the given equation and the steps to solve it step by step:
Given the equation: 47 × 98
Step 1: Express 98 as a combination of (47)'s and (2)'s. (98) can be written as (47 × 2).
Step 2: Substitute the expression for 98 in terms of 47 and 2 back into the equation:
47 × 98 = (47 × 47) - (2 × 47)
Step 3: Calculate the values on both sides of the equation.
- The left side: 47 × 98 = 4610.
- The right side:
- 47 × 47 = 2209
- 2 × 47 = 94
- Subtracting 94 from 2209 gives 2115.
Explanation:
1. We start with the equation 47 × 98, where 98 is represented as 47 × 2.
2. We substitute 98 in terms of 47 and 2 to get (47 × 47) - (2 × 47).
3. We calculate the values on both sides of the equation to find that they don't match. This indicates that the original equation is not true.

The answer to your question is:
2 and -49
Step-by-step explanation:
2 x -49 = -98
2 + (-49) = -47
x2 - 47x - 98 = 0
The solution to factor the quadratic equation above is:
(X + 2 ) (X - 49)
Since 2 and -49 multiply to -98 and add up -47, you know that the following is true:
x2 - 47x - 98 = (X + 2 ) (X - 49)
