Summary Introduction

To determine: The expectations for 500 red, 540 white

Introduction: The Chi-square value is a single number that adds up all the differences between our actual data and the data expected if there is no difference. If the real data and expected data are identical, the Chi-square value is 0.

d.

Summary Introduction

To determine: The expectations for 50 red, 54 white.

Introduction: The Chi-square test is intended to test how likely it is that an observed distribution is due to chance. It is also called a "goodness of fit" statistic because it measures how well the observed distribution of data fits with the distribution that is expected if the variables are independent.
