Study Notes
Determining Distribution of Emails
- To determine if the number of emails follows a uniform distribution, a chi-squared goodness of fit test should be performed.
Expected Emails per Day
- David was expecting to receive an equal number of emails each day, implying a uniform distribution.
Chi-Squared Test Statistic Formula
- The formula for calculating the chi-squared test statistic is: χ² = Σ [(Oi - Ei)² / Ei], where Oi is the observed frequency and Ei is the expected frequency.
Chi-Squared Test Statistic for the Given Data
- The chi-squared test statistic for the given data needs to be calculated using the formula and the provided data.
