A report just came out that stated that 21.1% of all Americans say that vanilla is their favorite ice cream, 20.9% say that chocolate is their favorite, 9.1% favor butter pecan, 9.5% favor strawberry, and the rest have other favorites. An ice cream shop owner thinks that her customers are not like the rest of America. The table below shows the results of 980 of her patrons' ice cream selections. What can be concluded at the αα = 0.10 significance level? Complete the table by filling in the expected frequencies. Round your answers to the nearest whole number.
