Chapter 11: Q. 46 (page 657)

A meteorologist wants to know if East and West Australia have the same distribution of storms. What type of test should she use?

Short Answer

Expert verified

The meteorologist will use the homogeneity test.

Step by step solution

01

Concept introduction

A hypothesis is a reasonable assumption for a behaviour (plural hypotheses). The scholarly approach involves that an assumption be validated before it can be deemed a factual prediction. Technical speculations are mainly influenced by past results that cannot be fully addressed by established scientific findings.

02

Explanation

It can be used to see if two populations have the same distribution or not. The confidence intervals for a testing of homogeneity are generated using the same methods as for a statistical technique. The independence analysis determines at whether two or more variables are mutually excluded.

Meteorologists are assessing whether East and West Australia are witnessing the same thunderstorm distribution. As a result, the meteorologist will use the homogeneity test.

A company packages apples by weight. One of the weight grades is Class Aapples. Class Aapples have a mean weight of 150g, and there is a maximum allowed weight tolerance of 5%above or below the mean for apples in the same consumer package. A batch of apples is selected to be included in a ClassAapple package. Given the following apple weights of the batch, does the fruit comply with the Class Agrade weight tolerance requirements. Conduct an appropriate hypothesis test.

(a) at the 5%significance level

(b) at the 1%significance level Weights in selected apple batch (in grams): 158; 167; 149; 169;164; 139; 154; 150; 157 ; 171; 152; 161 ; 141; 166; 172;

The table provides a recent survey of the youngest online entrepreneurs whose net worth is estimated at one million dollars or more. Their ages range from 17to 30. Each cell in the table illustrates the number of entrepreneurs who correspond to the specific age group and their net worth. Are the ages and net worth independent? Perform a test of independence at the 5%significance level.

Do families and singles have the same distribution of cars? Use a level of significance of 0.05. Suppose that 100randomly selected families and 200randomly selected singles were asked what type of car they drove: sport, sedan, hatchback, truck, van/SUV. The results are shown in Table 11.20.Do families and singles have the same distribution of cars? Test at a level of significance of 0.05.
