Question

Razzle Ice Cream is an ice cream shop chain that has locations all across the nation. Customers at Razzle Ice Cream have the option of ordering 1, 2, or 3 scoops of ice cream in their cone. The mean number of scoops ordered is =μ2.67, with a standard deviation of =σ0.79. Suppose that we will take a random sample of =n6 ice cream cone orders and record the number of scoops for each. Let x represent the sample mean of the number of scoops for the 6 ice cream cone orders. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed.(a)Find μx

(the mean of the sampling distribution of the sample mean).

=μx

(b)Find

σx

(the standard deviation of the sampling distribution of the sample mean).

=σx

Please let me know if there is a certain calculator that I can use to solve the questions because I super lost. Thanks

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
