b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
This means that we are 95% sure that the true duration of a typical cold(population mean) for all health adults in Georgia is between 6.9 and 8.2, which means that the correct answer is given by option b.
Answer:
11) 2 x 3.14 x (19/2) > (we want to use the radius)
2 x 3.14 x 9.5 = 59.66
12) 2 x 3.14 x (11/2) > (we want to use the radius)
2 x 3.14 x 5.5 = 34.54
34.54/2 + 11 = 28.27 >(becuase it is only a semicircle)
the plus 11 is the diameter, because the cirlce is cut in half
