Question

Since previous studies have reported that elite athletes are often deficient in their nutritional intake (for example, total calories, carbohydrates, protein), a group of researchers decided to evaluate Canadian high-performance athletes. A total of n = 324 athletes from eight Canadian sports centers participated in the study. One reported finding was that the average caloric intake among the n-208 women was 2,403.7 kilocalories per day (kcal/d). The recommended amount is 2,807.5 kcal/d. Is there evidence that female Canadian athletes are deficient in caloric intake? Is this result significant at the 5% level? a) State the appropriate Hn and Ha to test this. H0: μ-2,807.5 kcal/d; 0 H0: μ > 2,807.5 kcal/d; O Ho: μ-2,807.5 kcal/d; : Ho: μ 2,807.5 kcal/d; O Ho: μ . 2,807.5 kcal/d; Ha: μ # 2,807.5 kcal/d Ha: μ-2,807.5 kcal/d Ha: μ > 2,807.5 kcal/d Ha: μ-2,807.5 kcal/d H., μ < 2,807.5 kcal/d (b) Assuming a standard deviation of 810 kcal/d, carry out the test. (Round your value for z to two decimal places and round your P-value to four decimal places.) P-value- Interpret the result in plain language. O There is weak evidence of below-recommended caloric consumption among female Canadian high-performance athletes. O There is strong evidence of above-recommended caloric consumption among female Canadian high-performance athletes. O There is weak evidence of above-recommended caloric consumption among female Canadian high-performance athletes There is strong evidence of below-recommended caloric consumption among female Canadian high-performance athletes No interpretation can be made.
