Given in the table are her data.Type of foodCountRamen Tacos Pizza1822 39Hamburgers21An appropriate null hypothesis to test whether the foodchoices are equally popular is=Ho PR PT = PP = PH = 0.25 is the proportionof students in the sample who chose ramen, and soon.=Ho: μ25, where μ = the mean number ofstudents that prefer each type of food.Ho PR PT = PP = PH-= 0.25, where pR is theproportion of students in the school who wouldchoose ramen, and so on.Ho : p = 0.25, where p = the proportion of allstudents who prefer ramen.Ho : nr = nr = np = nH= = 25, where ng is thenumber of students in the school who would chooseramen, and so on.

There is total 4 type of foods. Suppose pR, pT, pP, and pH define the proportions of students in the…
