Question

A research firm claims that the distribution of the days of the week that people are most likely to order food for delivery is different from the distribution shown in the pie chart. You randomly select 491 people and record which day of the week each is most likely to order food for delivery. The table to the right shows the results. At $\alpha = 0.01$, test the research firm's claim. Day Frequency, $f$ Sunday 44 Monday 18 Tuesday 20 Wednesday 48 Thursday 42 Friday 164 Saturday 155 $H_0$: The distribution of the days people order food for delivery is uniform. $H_a$: The distribution of the days people order food for delivery differs from the expected distribution. Which hypothesis is the claim? $H_a$ Calculate the test statistic. $\chi^2 = \text{_}$ (Round to three decimal places as needed.) Determine the $P$-value. $P = \text{_}$ (Round to three decimal places as needed.)
