Subtract 18d from both sides
subtract 9k from both sides
simplify 5k + 10 - 18d - 9k to -4k + 10 - 18d
factor out the common term 2
divide both sides by 2
cancel 2 and now simplify brackets
Answer: D) m < -2k + 5 - 9d or the fourth option.

<h3>How to determine the standard deviation of the sample mean differences?</h3>
The table of values is given as:
<u>Sample Standard deviation</u>
Red box 3.868
Blue box 2.933
The standard deviation of the sample mean differences is calculated using:

This gives

Evaluate the expression

Also, the table of value do not give any information regarding the sample size.
This means that the sample size of the session regarding the number of people would purchase the red box and the blue box are unknown
Hence, the standard deviation of the sample mean differences is 4.854
