To find: the number and type of variables.

Answer to Problem T1.1SPT
2 quantitative, 1 Categorical
Explanation of Solution
Variables are age, marital status and earned income of a sample of 1463 women
Age is a quantitative variable, since the ages comes under the numerical values
Marital status is a categorical variable; the reason is that it has options Married, Divorced, Widowed etc.
Earned income is a quantitative variable; because it comes under the numerical values like $200.
Therefore it is observed that there are 2 quantitative variables and 1 categorical variable.
Hence, the correct option is (d)

- Can you help me solve problem 38 with steps im stuck.arrow_forwardHow do the samples hold up to the efficiency test? What percentages of the samples pass or fail the test? What would be the likelihood of having the following specific number of efficiency test failures in the next 300 processors tested? 1 failures, 5 failures, 10 failures and 20 failures.arrow_forwardThe battery temperatures are a major concern for us. Can you analyze and describe the sample data? What are the average and median temperatures? How much variability is there in the temperatures? Is there anything that stands out? Our engineers’ assumption is that the temperature data is normally distributed. If that is the case, what would be the likelihood that the Safety Zone temperature will exceed 5.15 degrees? What is the probability that the Safety Zone temperature will be less than 4.65 degrees? What is the actual percentage of samples that exceed 5.25 degrees or are less than 4.75 degrees? Is the manufacturing process producing units with stable Safety Zone temperatures? Can you check if there are any apparent changes in the temperature pattern? Are there any outliers? A closer look at the Z-scores should help you in this regard.arrow_forward
