Given the population 3, 5, 8, 9, and 10. Suppose samples of size 4 are drawn from this population
1. What is the mean (u) and standard deviation (a) of the population?
2. How many different samples of size n& can be drawn from the population? List them
corresponding means. 3. Construct the sampling distribution of the sample means
4 What is the mean () of the sampling distribution of the sample means? Compare this to the mean
the population
5. What is the standard deviation (n) of the sampling distribution of the sample means? Compare thin
the standard deviation of the population.

The following data show the number of cars sold at a dealer during the past 20 weeks:
18; 13; 2; 20; 8; 10; 5; 10; 6; 9; 10; 20; 2; 15; 16; 16; 13; 10; 17; 10
Use the data to construct a histogram that shows the number of weeks versus car sales. Use the intervals
0,5 − 4,5; 4,5 − 8,5; 8,5 − 12,5; 12,5 − 16,5; 16,5 − 20,5
for the number of cars sold. The correct histogram

Three resistors with values of 60.0 Ω, 30.0 Ω,
and 20.0 Ω, respectively, are connected in
series to a 110.0 V battery of negligible
internal resistance. Draw a circuit diagram
and find the (a) equivalent resistance of
the combined resistors, (b) current flowing
through each resistor, (c) voltage drop
across each resistor, and (d) the power
dissipated by each resistor.
