Answer:
The point estimate for the number of pieces per package is of 18.72.
Step-by-step explanation:
Point estimate of a population mean:
The mean of the sample gives an estimate for the population mean.
They find that the sample mean number of pieces is 18.72.
This means that the point estimate for the number of pieces per package is of 18.72.
54 = 2 x 3³
So, if a and b are integers, a=2 and b=3
Subtract to find the amount of the increase then divide the amount of increase by the original amount:
2.46 - 2.22 = 0.24
0.24/2.22 = 0.108
Multiply by 100 to get percent:
0.108 x 100 = 10.8%
Rounded to nearest whole number = 11%
