A nutritionist claims that individuals tend to report decreasing dietary intake the more they are interviewed. To investigate this claim, a random sample of eight female university students was asked to record their dietary intake for two consecutive days. An analysis on their total dietary intake (in kcal) gave the following results: Student 1 3 4 7 8 Day 1 1905 2237 1863 2291 2211 1428 1062 1705 Day 2 1658 1479 1100 2116 1999 1097 1283 2424 Assume that the differences in total dietary are normally dsitributed. Using a 5% level of significance, test the claim that a higher dietary intake is observed on day 1.
