The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 222 residents whose mean number of pounds of trash generated per person per week was 36.9 pounds and the standard deviation was 8.9 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean number of pounds per person per week is between and pounds. C. If many groups of 222 randomly selected members are studied, then a different confidence interval would be produced from each group. About 95 V percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person percent will not containthe true population mean number of per week and about pounds of trash generated per person per week.

Concept explainers

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

Question

The mayor is interested in finding a 95% confidence interval for the mean number of pounds of
trash per person per week that is generated in the city. The study included 222 residents whose
mean number of pounds of trash generated per person per week was 36.9 pounds and the
standard deviation was 8.9 pounds. Round answers to 3 decimal places where possible.
a. To compute the confidence interval use a
distribution.
b. With 95% confidence the population mean number of pounds per person per week is between
and
pounds.
C. If many groups of 222 randomly selected members are studied, then a different confidence
interval would be produced from each group. About 95
percent of these confidence
intervals will contain the true population mean number of pounds of trash generated per person
percent will not contain the true population mean number of
per week and about
pounds of trash generated per person per week.

You want to buy a washing machine, and a salesperson tells you that the mean repair costs for Model A and Model B are equal. You research the repair costs. The mean repair cost of 29 Model A washing machines is $211. Assume the population standard deviation is $15. The mean repair cost of 26 Model B washing machines is $216. Assume the population standard deviation is $25. At a = 0.01, can you reject the salesperson's claim? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). O A The mean repair cost for Model A is greater than Model B B. The mean repair costs for Model A and Model B are equal. O C.
