Answer:
a) 0.3495
b) (9.65, 10.35)
Step-by-step explanation:
We are given the following in the question:
Sample mean, = 10 hours
Sample size, n = 64
Alpha, α = 0.02
Population standard deviation, σ = 1.2 hours
a) Margin of error
Formula
Putting values, we get,
b) the sample mean is 10 hours, then the 98% confidence interval
Putting the values, we get,
Each hour, the amout remaining is multiplied by
.. 1 -5.2% = 0.948
Your exponential equation can be written as
.. amount = (starting amount)*(hourly multiplier)^(number of hours)
.. D = 500*0.948^t
4x-3+7x+1
Ones with a variable: 4 & 7
Only whole number: -3 & 1
The answer is option two: -3 and 1; 4x and 7x
It belongs to rational numbers and intergers
