6. The American Dietetic Association recommends a dietary intake of 2,000 calories per day. A sample of 438 college athletes in a study of obesity report a mean intake of 2,812 calories per day, with a standard deviation of 206 calories. Based on the sample data, is the caloric intake of college athletes greater than the American Dietetic Association’s recommendations? Run the appropriate test at a 5% level of significance.

Solutions

Expert Solution


Conclusion

It is concluded that the null hypothesis Ho is rejected. Therefore, there is enough evidence to claim that the caloric intake of college athletes greater than the American Dietetic Association’s recommendations at the 0.05 significance level.

An animal’s maintenance caloric intake is defined as the number of calories per day required to maintain its weight at a constant value. We wish to discover whether the median maintenance caloric intake, m, for a population of rats is less than 10g/day. We draw a SRS of 17 rats, feed each rat 10g of dry food per day for30 days, and find that 4 of the rats lost weight, while the rest gained weight. (a) State null and alternative...
