Step-by-step explanation:
The average amount of the exercise hours at the same time as I am at my home town is 50 hours a month
Does this diverge from average exercise while I am not in my home town? This is 46 hours
So,
Null: H0: μ = 30
H1: μ ≠ 30
Two tail test
Formula:
z = (46 - 50)/SD
75.25x + 3604 = 300.50x
300.50x - 75.25x = 3604
225.25x = 3604
x = 16
Both companies charged the same at 16 tons
first answer 16 tons
--------------------
300.50x = 300.50(16) = $4,808
both companies charged the same are $4,808
second answer is $4,808
