Answer:
A confidence interval for a mean should be constructed to estimate the variable of interest.
Step-by-step explanation:
The confidence interval for a mean uses the sample mean to estimate the true population mean. Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean. In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.
Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations

Arrange equation variables for elimination

Multiply -y+x=2 by 2: -2y+2x=4

so adding




so the system of equations becomes

0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!
Answer:
Range is all real numbers
Step-by-step explanation:
The term that completes the blank and fits the description is an array
<h3>How to complete the blank?</h3>
From the question, we understand that:
- The variable term holds multiple values
- It uses square brackets
- it is defined by a single variable
The term that fits the above highlights is array
Hence, the complete statement is:
<em>array can hold multiple values within a single variable and is defined by having values between square brackets.</em>
