Statistics: Ch 9 Hypothesis Testing (15 of 35) Null Hypothesis Example: Air Quality

To donate:

A Null Hypothesis example:
If the air quality index (AQI) is grater than 100, air is unhealthy;
If the AQI is less than equal 100, air is healthy.
An ecologist is trying to show that the air in LA is unhealthy. The null hypothesis defines THE OPPOSITE of what you are trying to show.

Ha @Michel,

Ga zo door, hoop deze statistiek lijst inclusief annova en binnenkort @getallen theorie en @cryptografie gemaakt wordt. Je maakt mij er enorm blij mee.

Even een vraagje: is er een lijst in je natuurkunde lessen die verband heeft met lineair algebra? De applicatie daarvan namelijk in netwerken bedrijven enz?

Alvast dank voor je reactie.
