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
Answer:
500x1.5
Step-by-step explanation:
X= the fee that is paid montly
725= 125+12x
12 represent 12 months in a year multiplied by the fee paid each month plus the registration fee.
Area of course also just a reminder Area is measured in square units such as square centimteres, square feet, square inches, etc
=153/300
=.51
The probability is .51 or 153/300
