HO

HW

Two Exercises Solutions to Two Problems


Tuesday

Practice

Finishing the two problems + working on MathXL For School> Significance Testing Pop Std Dev Known Due Thursday night at midnight. This does contain some required review from the last couple of weeks.


Wednesday

Learning Targets for the next few days:

  1. Understand when to use t-procedures for a single sample and how they differ from the z-procedures covered earlier
  1. Understand what a t-distribution is and how it differs from a normal distribution. <link>
  2. Know how to check whether the underlying assumptions for a t- test or t-confidence interval are reasonably satisfied.
  3. Be able to calculate a t-confidence interval for a population mean.
  4. Be able to test a population mean with a t-test. Be able to calculate the t-test statistic and to determine the p-value as an area under a t-density curve.

Today we will watch this video <link>

We will learn how to use StatCrunch to test to see if the small sample could have come from a Normally distributed parent population

We will use this StatCrunch File <link>

We will also learn how to use StatCrunch to run a test of significance

Statistics Week 24 ending 2/15

Will a couple of you plug the Chromebooks in and wheel it back down to my room along with the calculators?


Thursday

I am not here. You have to finish up this assigned work. If you are finished, you may read LTT Chapters 14 and 15 and write a 100+ word reflection in Moodle.

HW:

  • All work is due by Midnight
  • Read the Investigative task. Be ready to ask questions Friday.

Friday

In class:

I am assessing how well you can:

  1. Understand statistics as a process for making inferences about population parameters based on a random sample from that population.
  2. Define a random variable for a quantity of interest by assigning a numerical value to each event in a sample space; graph the corresponding probability distribution using the same graphical displays as for data distributions.
  3. Analyze decisions and strategies using probability concepts

In addition to Running Start objectives around estimating population parameters.

  • Take a look at the investigative task.
  • Time to work on it.
  • Your final report is due Monday @ the start of class.
