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

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...
