Hypothesis tests for two samples- powerpoint


You are a statistician started for a garbage congregation. A few new scientists own been paid by your congregation. They are experts in pharmacology, but are not experts in doing statistical studies, so you conciliate decipher to them how statistical studies are performed when examinationing two exemplifications for the virtue of a new garbage. The two exemplifications can be subject or dogged, and you conciliate decipher the disagreement.

Concept entity Studied

Your convergence is on theory examinations and self-reliance space-betweens for two populations using two exemplifications, some of which are insubject and some of which are subject. These concepts are an production of theory examinationing and self-reliance space-betweens which use statistics from one exemplification to gain conclusions environing population parameters.

What to Submit

To exhaustive this assignment, you must highest download the worksheet and then exhaustive it.

You conciliate too unravel a PowerPoint grant for the newly paid scientists on these topics, and you own been asked to collect two real-life models that you conciliate portray step-by-step. Your boss has asked you to apprehend the subjoined slides:

Slide 1: Title slide

Slide 2: Describes the two disagreements betwixt insubject and subject exemplifications

Slide 3: Provides an model of insubject exemplifications when examinationing a new garbage

Slide 4: Shows how to set up a theory examination for two insubject rates: One to examination whether they are similar and another one to examination whether one rate is larger than the other

Slide 5: Shows the formula for the examination statistic for two insubject rates and lists what each changeable in the formula represents

Slide 6: Shows the formula for the brink of fault (E) when doing a self-reliance space-between on two rates and deciphers what each changeable stands for

Slide 7: Other than rates, portrays what other types of theory examinations can be performed for two insubject exemplifications

Slide 8: Provides an model of subject exemplifications (too known as matched pairs) when examinationing a new garbage. The two exemplifications should be a anteriorly and behind examination after a while the corresponding group

Slide 9: Shows the t formula for the examination statistic for matched pairs and deciphers what each changeable represents

Slide 10: Show what a self-reliance space-between for matched pairs would contemplate affect using simply changeables. Also, apprehend the formula for the Brink of Fault and say what each changeable represents

To parade the formulas aloft, you may deficiency to use the subjoined changeables which you can representation from here:

x̅, p̂, q̂, p̅, q̅, d̅, ∑, μ, σ, σ2, α
