The amount of sodium (in milligrams) in one serving for a random sample of three different foods is listed in the table below. At the 0.10 level of significance, is there sufficient evidence to conclude that a difference in mean sodium amounts exists among the condiments, cereals, and desserts?
Condiments Cereal Desserts
270 260 100
130 220 180
230 290 250
180 290 250
80 200 300
70 320 360
200 140 300
I am using an ANOVA test for this question, but am having trouble stating the null and alternative hypotheses.....
Are they:
H0 u condiments = u cereal = u desserts
Ha The means are not all equal
I got a P value of 0.09239 so there is not enough evidence to support the claim that there is a significant difference in mean sodium between condiments, cereal and desserts, but how do I write the conclusion for this?
