Given : Significance level : 
Critical value : 
By using the standard normal distribution table for z, we find the critical value of 
corresponds to the p-value 0.03.
Hence, the z-value that was used in the computation must be 1.88 .

Step-by-step explanation:
To find miles per hour, divide miles by hours:
(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = (17/8) mi/h = 2 1/8 mi/h
Hours per mile is the reciprocal of that:
1/(17/8 mi/h) = 8/17 h/mi
The Breakeven revenue for the retail business is Birr 12,500
<h3>What is
breakeven?</h3>
Breakeven is the point at which the revenue is equals to the cost, hence the profit is zero.
Revenue = Cost
Let x represent the number of items sold, hence:
Revenue = (100% + 25%) of x = 1.25x
Cost = 5% of x + 12000 = 0.05x + 12000
At breakeven:
1.25x = 0.05x + 12000
x = 10000
Hence:
Revenue = 1.25(10000) = Birr 12,500
The Breakeven revenue for the retail business is Birr 12,500
