Answer:
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102
Step-by-step explanation:
We can build an estimate from a sample, and this estimate will be the best estimate for the proportion of the population.
Sample:
50 subscribers
15 own fewer than 2 vehicles
Proportion:
15/50 = 0.3 = 30% own fewer than 2 vehicles.
Based on the data, what is the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles?
340 subscribers
The most reasonable estimate for this number is 0.3*340.
0.3*340 = 102
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102

This means that 
Random sample of 100 screws.
This means that n = 100.
To see if the batch of screws has a significantly different mean length from 3 inches, what would the value of the z-test statistic be?
3 inches, so
