Question

A researcher takes sample temperatures in Fahrenheit of 16 days from Miami and 14 days from Atlanta. Use the sample data shown in the table.

Test the claim that the mean temperature in Miami greater than the mean temperature in Atlanta. Use a significance level of α=0.10α=0.10.
Assume the populations are approximately normally distributed with unequal variances.
Note that list 1 is longer than list 2, so these are 2 independent samples, not matched pairs.

Miami	Atlanta
68.3	73.6
83.1	69.3
79.1	54.9
72	81.1
72.8	78.6
83.3	54
82.7	36.1
80.7	44.3
87	58.4
83.1	50.8
77.4	60.5
86.1	61.2
76.3	46.8
74.5	54.4

The Null Hypotheses is: H₀: μ1 - μ2 = 0

What is the alterative hypothesis? Select the correct symbols for each space. (Note this may view better in full screen mode.)

H_A: μ1 - μ2

Based on these hypotheses, find the following. Round answers to 4 decimal places.

Test Statistic =

p-value =

The p-value is

The correct decision is to .

The correct summary would be: the claim that the mean temperature in Miami greater than the mean temperature in Atlanta.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
