An investigator wants to estimate the average daily energy intake in H of females

An investigator wants to estimate the average daily energy intake in kJ of femalese in a location. Eleven females were selected and their daily energy intake ise 5260; 5470; 5640; 6180; 6390; 6515; 6805; 7515; 7515; 8230; 8770:e Assume that the number of females in this location is large. 1. Estimate the average daily energy intake of females and construct a 95% confidence interval.e 2. We want to do the same study in Toronto. To achieve a precision e = 100 with the confidenke level a = 0:05 in our survey, what should be our sample size?e
