Answer:
I would order the pizza from first shop because it has lower standard deviation and in this way i will know when the pizza will delivered.
Step-by-step explanation:
Mean time taken by first pizza shop is 46 minutes with standard deviation of 4 minutes it means this shops deliver a pizza in 42 to 48 minutes
on the other hand mean time taken by second pizza shop is 44 minutes with standard deviation of 18 minutes it means this shops deliver a pizza in 26 minutes (44-18) to 62 minutes (44+18)
I would order the pizza from first shop because it has lower standard deviation and in this way i will know when the pizza will delivered.
