A simple random sample of 5 months of sales data provided the following information: Month:12345 Units Sold:9480859492 (a)Develop a point estimate of the population mean number of units sold per month. x

89 units

Step-by-step explanation:

-The population's mean point estimate is equivalent to the sample mean.

Given the 5 month units sold is 94,80,85,94 and 92

-Mean is the average of the units sold over the 5 month period:

Hence, the point estimate for the population mean is 89 units

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

1) 2/5

2) zero=0/1

3) zero=0/2
