In Spring 2017, data was collected from a random selection of STA 2023 students. One of the questions asked how many hours they
Arte-miy333 [17]

Answer: 0.22

Step-by-step explanation:

We know that the best point estimate for the difference between two population mean is the difference between their sample means.

Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.

Let A denotes the population of upperclassmen and B denotes the population of underclassmen .

\overline{x}_A=0.12

\overline{x}_B=0.34

Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

\overline{x}_B-\overline{x}_A=0.34-0.12=0.22

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22

a car covers a distance of 490 km with a speed of 70km and then covers a speed of 90km calculate its average speed
DaniilM [7]
Average speed = total distance divided by total time.

In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.

There are 45 vehicles in a parking lot. Three fifths of the vehicles are minivans. How many of the vehicles in the parking lot a
suter [353]

Answer: There are 27 minivans out of the vehicles in the parking lot.

Step-by-step explanation:

Since we have given that

Number of vehicles in a parking lot = 45

Part of the vehicles are minivans is given by

\frac{3}{5}

Number of vehicles in the parking lot are minivans is given by

\frac{3}{5}\times 45\\\\=3\times 9\\\\=27

Hence, there are 27 minivans out of the vehicles in the parking lot.
