Answer:
yes, we can reject the hypothesis
Step-by-step explanation:
The null hypothesis
H0 = mean weekly food budget for all households in this community is $98
Let´s find z
z= (x – mean) / standard deviation / √sample size
z = (100 – 98) / 10 / √100
z = 2
Using a Z table we can find probability
P (z>2) = 0.0228
Since P < α , results are significant and we can reject the hypothesis
5 pounds of banana = 5 x $0.8 = $4
5 pounds of apple = 5 x $ 1.4 = $7
total cost = $4 + $7 = $11
Answer:

This means that there is a division needed. Divide the price by yards.
So
Price/Yards = 44 ÷ (3⅔) = 12 Dollars per Yard.
