Here, we calculate the mean of the given sample to get the sample mean. We can then say that the sample mean calculated is a point estimate for the population mean
However some error can take place since we are using only a subset of the population to calculate the point estimate for the population mean. This error is called as sampling error. This would be the best estimate for the population mean
Sample mean speed of the Ferris wheel is = average of all the 10 individual values = (10+10+12+14+10+9+8+14+12+15)/10 = 11.4 miles per hour
Best estimate for population mean = 11.4 miles per hour
