Consider the following set of sample data: (34, 32, 34, 32, 40, 37, 31, 31, 29, 27). We're interested in using this data to test
a null hypothesis about the population mean. Which of the following statements are true? I. Assuming this represents a random sample from the population, the sample mean is an unbiased estimator of the population mean.
II. Because they're robust, t procedures are justified in this case.
III. We'd use zprocedures here, since we're interested in the population mean.
a. I only
b. II only
c. III only
d. I and II only
e. I and III only
I. Assuming this represents a random sample from the population, the sample mean is an unbiased estimator of the population mean.
II. Because they're robust, t procedures are justified in this case.
The t procedures are utilized because they are used as a hypothesis testing tool, which allows for testing of an hypothesis applicable to a population where in this case we are testing the null hypothesis about the population mean.
your answer is B because with A the size of the dog cant lower and with D if there is less clothing then there cant more people and last we have C it cant be C because the more people there is the more the temp gets hotter not colder
Let x: number of regular basketball y: number of long-distance basket We have the following system of equations: 2x + 3y = 96 x + y = 45 Solving the system we have y = 45-x 2x + 3 (45-x) = 96 2x +135 -3x = 96 -x = 96 -135 x = 39 Then, y = 45-x y = 45-39 y = 6 answer were made regular baskets = 39 long-distance baskets = 6
False, all integers are rational because they can be expressed as a fraction. Like -4 is a rational number because it can be -4/1. All integers are rational.
