Answer:
(3138.29, 3705.11)
Step-by-step explanation:
Given that for sample size of n = 50 male athletes from eight Canadian sport centers surveyed, the average caloric intake was 3077.0 kilocalories/day with a sample standard deviation of 987.0.
The recommended amount = 3421.70
To construct 95% confidence interval
Since population std deviation is not known we use t critical value for degree of freedom 50-1 =49
t critical = 2.010
Hence margin of error =
Confidence interval lower bound =
Confidence interval upper bound =
Conf interval =
