Homepage Univerity of North Georgia Moore BPs Araignment points l Previous Answers Mint osuas eE o/2 previous studies have reported that athletes in Ask Your Teach Canadian are often their nutritional intake (or example, total calories, carbohydrates, protein), a group of researchers decided to evaluate n 201 women was 2,403.7 total of 324 from eight Canadian sports centers participated in the study, one reported finding was that the average caloric intake a the at the 5% level? kilocalories per day (kcal/d). The recommended amount is 2,817,s kcavd. Is there evidence that female Canadian athletes are deficient in caloric mtake? sthis suk (a) State the appropriate Ho and He to test this, o Ho: 2,817 s koal/d: Ha: 2,817.5 kcavd Ho: R-2,817.5 kcal/d; Ha: H 2,817.5 kcavd Ho: 2,817.S kcal/d; Ha: u 2.8175 kcal/d Ho: u 2,817.5 kcal/d: Ha: 2 817.5 kcald Ho: R 2,817.5 kcaVd: Ha: 2,817.5 kcal/d (b) Assuming a standard deviation of B30 kcavd, carry out the test. (Round your value for z decimal places and round your P value to four decimal places.) to two Interpret the result in plain language. There is weak evidence of below recommended caloric consumption among female canadan high performance athletes, There is strong evidence of above-recommended caloric consumption among female Canadian high-performance athletes, There is weak evidence of above recommended caloric consumption among female canadan high-performance athletes, O There is strong evidence of below recommended caloric consumption among female Canadian high performance athletes interpretation can be made.

Solution:-
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: > 2817.5
Alternative hypothesis: < 2817.5
Note that these hypotheses constitute a one-tailed test. The null hypothesis will be rejected if the sample mean is too small.
Formulate an analysis plan. For this analysis, the significance level is 0.05. The test method is a one-sample t-test.
Analyze sample data. Using sample data, we compute the standard error (SE), degrees of freedom (DF), and the t statistic test statistic (t).
SE = s / sqrt(n)
S.E = 58.544
DF = n - 1 = 201 - 1
D.F = 200
t = (x - ) / SE
t = - 7.07
where s is the standard deviation of the sample, x is the sample mean, is the hypothesized population mean, and n is the sample size.
The observed sample mean produced a t statistic test statistic of - 7.07. We use the t Distribution Calculator to find P(t < - 7.07) = less than 0.0001
Interpret results. Since the P-value (almost 0) is less than the significance level (0.01), we have to reject the null hypothesis.
There is evidence of below recommended caloric consumption among female Canadian high performance atheletes.
