One group of observations or one sample test

Suppose we wish to compare the mean dietary intake of a particular group of individuals with the recommended daily energy intake of 7846 kJ per day. The table below gives the average daily energy intake over ten days in 16 healthy women aged 24-28 years.

Average daily energy intake (kj)

5168 5249 5541 5687

5988 6285 6444 6523

6840 7400 7589 8571

8750 8800 8926 9108

Test the Hypothesis:

H_o: The average daily energy intake by the women is 7846 kj/day

H_a: The average daily energy intake by the women is not 7846 kj/day
