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
16.72p + 9 ≤ 133
16.2p ≤ 124
p ≤ 124 / 16.2
