Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
Interest rate= 0.083%
Step-by-step explanation:
Principal= $5000 Amount= $10000 Time period= 12 years
A=Amount, P= Principal, I= Simple Interest r= Rate of interest t= Time period
3
Because if you split something into 3, you have 3 thirds
1/3 + 1/3 + 1/3 = 3/3
