Answer: Null hypothesis :
Alternative hypothesis :
Step-by-step explanation:
Let be the proportion of women using supplements and be the proportion of women who did not to have died during that period .
Then the set of hypothesis for testing if the proportion of women elderly women who use dietary supplements is different than those who do not will be :-
Null hypothesis : [∵ it takes equality sign]
Alternative hypothesis : [∵ it takes ≠ sign to show difference]
1 foot = 12 inches.
0.75 feet x 12 inches per foot = 9 inches per day.
1 day = 24 hours.
9 inches / 24 hours = 0.375 inches per hour ( 3/8 inch per hour)
Not sure if you need a decimal or fraction for an answer so I provided both.

______________________________
<h3>1.) Combine like terms:</h3>
<em> - We do this because we need 1 Number/Variable left over. </em>
<u>Equation at the end of Step 1:</u>
- <u /><u />
<em />
<h3>2.) Add −17 and 31:</h3>
<em> - We do this because we can only have 1 number on each side of the equals. (This doesn't count towards the number connected to the variable.)</em>
<u>Equation at the end of Step 2:</u>
- <u /><u />
<h3>3.) Subtract 14 from both sides:</h3>
- Cancels Out
<em> - We do this because now we just need the 1 variable and the 1 number on opposite sides of the equal.</em>
<u>Equation at the end of Step 3:</u>
- <u /><u />
<h3>4.) Multiply both sides by 2:</h3>
- <em /><em> </em>× <em />
- <em /><em> </em>×
<em> - We multiply by 2 since we have a fraction. In this case the reciprocal is 2 meaning we multiply by 2. </em>
