Based on sales over a six-month period, the five top-selling compact cars are Chevy Cruze, Ford Focus, Hyundai Elantra, Honda Civic, and Toyota Corolla. Based on total sales, the market shares for these five compact cars were Chevy Cruze 24%, Ford Focus 21% Hyundai Elantra 20%, Honda Civic 18%, and Toyota Corolla 17%. Suppose a sample of 400 compact car sales in one city showed the following number of vehicles sold. Chevy Cruze 109 Ford Focus 91 Hyundai Elantra 63 Honda Civic 85 Toyota Corolla 52 Use a goodness of fit test to determine if the sample data indicate that the market shares for the five compact cars in this city are different than the market shares reported by Motor Trend. Use a 0.05 level of significance. State the null and alternative hypotheses. O Ho: The market shares for the five automobiles in this city differ from 0.24, 0.21, 0.20, 0.18, 0.17. H: The market shares for the five automobiles in this city are the same as the above shares. OH: The majority of the market shares for the five automobiles in this city are the same as the ones reported by Motor Trend. H₂: The majority of the market shares for the five automobiles in this city differ from the ones reported by Motor Trend.

OH: The majority of the market shares for the five automobiles in this city differ from the ones reported by Motor Trend. H: The majority of the market shares for the five automobiles in this city are the same as the ones reported by Motor Trend. Find the value of the test statistic.
