One of the products produced by Branco Food Company is All-Bran Cereal, which competes with three other brands of similar all-bran cereals. The company's research office wants to investigate if the percentage of people who consume all-bran cereal is the same for each of these four brands. Let us denote the four brands of cereal byA,B,C, andD. A sample of700persons who consume all-bran cereal was taken, and they were asked which brand they most often consume. Of the respondents,190 said they usually consume BrandA,157consume BrandB,200 consume BrandC, and153 consume BrandD. Does the sample provide enough evidence to reject the null hypothesis that the percentage of people who consume all-bran cereal is the same for all four brands? Use=0.025.

Round your answer to three decimal places.

2=

(b) Using=0.025, can you conclude that the current percentage distribution is different from the hypothesized one?

We conclude that the current percentage distribution

is different or is not different from the hypothesized one. (Pick one a. is different b. is not different)
