#29). This is 1 question. Need help with test statistic and p value.
According to a report published by the USDA 3 years ago, a typical American consumes an average of 27 pounds of ice cream per year. A researcher at the USDA would like to determine if the average amount of ice cream consumed each year by a typical American has changed since the original report was published. The researcher collected data from a random sample of 63 Americans and found that the mean amount of ice cream consumed each year by the sample was 27.78 pounds with a standard deviation of 1.92 pounds. Using a significance level of 1%, test the hypothesis that the mean amount of ice cream consumed each year by a typical American is different than 27 pounds. Use the p-value method.

O The sample data provide sufficient evidence to reject the null hypothesis that the mean amount of ice cream consumed each year by a typical American is 27 pounds and thus we conclude that the mean amount of ice cream consumed each year by a typical American is likely different than 27 pounds. The sample data provide sufficient evidence to reject the alternative hypothesis that the mean amount of ice cream consumed each year by a typical American is different than 27 pounds and thus we conclude that the mean amount of ice cream consumed each year by the typical American is likely 27 pounds. The sample data do not provide sufficient evidence to reject the alternative hypothesis that the mean amount of ice cream consumed each year by a typical American is different than 27 pounds and thus we conclude that the mean amount of ice cream consumed each year by the typical American is likely different than 27 pounds.
