a) The tables for both plans are attached.
b) The graph of both plans are attached.
c) If Gertrude is going to make less than 100 calls per month the best plan is Global Cellular. On the other hand, if Gertrude is going to make more than 100 calls per month the best option is Super Cell.
Step-by-step explanation:
a) We make a table for both companies. You can see that making 100 calls is the same cost per month in both companies.
Super Cell: M(100)=0.15×100+10= $25
Global Cellular: M(100)=0.25×100= $25
b)In the picture attached is shown the graph of both companies. The red line shows the graph of Super Cell plan and the blue line shows the graph of Global Cellular plan.
c) If Gertrude is going to make less than 100 calls per month the best plan is Global Cellular. Because blue line is below the red one(that means Super Cell is cheaper)
On the other hand, if Gertrude is going to make more than 100 calls per month the best option is Super Cell. Because red line is below the blue one(that means Global Cellular is cheaper)

Step-by-step explanation:
Given that the owner of the local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas.
Sample size = n =45: Sample mean= x bar = 31.4 and s = 4.5
Std error of sample =
(One tailed test at 5% )
Mean difference = 1.4
Test statistic = Mean diff/se = 2.087
(t test only can be used as population std dev not known)
p value = 0.0218
Since p <0.05 our alpha, we reject null hypothesis.
There is a strong evidence that on average it takes more than 30 minutes for home delivery
