Week 6

Monday

Bellringer

Test corrections - if you did not get 100% correct the problems you missed. Explain your solutions.

The solutions are on google classroom.

Turn in the corrections. You will get half of the point you missed back.

Define the vocabulary for Ch 8 on Google Classroom

Objectives

  • Determine the point estimate and margin of error from a confidence interval.
  • Interpret a confidence interval in context.
  • Interpret a confidence level in context.
  • Describe how the sample size and confidence level affect the length of a confidence interval.
  •  Explain how practical issues like nonresponse, undercoverage, and response bias can affect the interpretation of a confidence interval.

     

Agenda

8.1 Exercises # 1-8

When it asks you to sketch, do that on your own paper, you do not have to turn that in. You can just type the numbers that will be on the x-axis, without the normal curve above.

 

Wednesday

Bellringer

Zoom session to cover Confidence Intervals, critical values, and sample sizes

Objectives

  • State and check the Random, 10%, and Large Counts conditions for constructing a confidence interval for a population proportion.

  •  Determine critical values for calculating a C % confidence interval for a population proportion using a table or technology.

  •  Construct and interpret a confidence interval for a population proportion.

  • Determine the sample size required to obtain a C % confidence interval for a population proportion with a specified margin of error.

Estimating a population mean

Objectives

  • State and check the Random, 10%, and Normal/Large Sample conditions for constructing a confidence interval for a population mean.
  •  Explain how the t distributions are different from the standard Normal distribution and why it is necessary to use a t distribution when calculating a confidence interval for a population mean.
  •  Determine critical values for calculating a C% confidence interval for a population mean using a table or technology.
  •  Construct and interpret a confidence interval for a population mean.
  • Determine the sample size required to obtain a C% confidence interval for a population mean with a specified margin of error.
