The value of the printer on the first year was $ 23,750.00. On the second year it was $ 22,562.5. On the third year it was $ 21,434.38.
Step-by-step explanation:
Since the printer depreciates at a rate of 5% per year, I believe the stated equation is miss typed. Therefore I'll answer this with the correct equation that would represent that setting:
In the first year the value of the printer is:
On the second year the value of the printer is:
On the third year the value of the printer is:
The value of the printer on the first year was $ 23,750.00. On the second year it was $ 22,562.5. On the third year it was $ 21,434.38.
Answer:
The value of the test statistic z for this hypothesis test is -2.79
Step-by-step explanation:
Consider the provided information.
To calculate the test statistic use the formula:
Where, z is Test statistics, n is Sample size, p₀ = Null hypothesized value and = Observed proportion.
p₀ = 0.50
Thus 1-p₀= 0.50
42% responded that if they had a cell phone, thus
The sample size is 305.
Substitute the respective values in the above formula.
Hence, the value of the test statistic z for this hypothesis test is -2.79
