We wish to know if we can conclude that the mean daily caloric intake in the adult rural population of

a developing country is less than 2000. A sample of 500 had a mean of 1985 and a standard deviation

of 210. Let alpha = .05

A population of men is monitoring their daily caloric intake for training purposes. They find that their caloric intake is approximately normally distributed with a population mean of 2500 calories and a population standard deviation of 500 calories. Find the probability that a randomly selected male from this population has a caloric intake of between 1500 and 3500. Find the probability that a randomly selected male from this population has a caloric intake less than 1500. Find the 93rd percentile...

Day 1 Caloric intake: 859 kcals Day 2 Caloric Intake: 1207 kcals Day 3 Caloric Intake: 437 kcals It has been postulated that an excess of 3,500 calories = 1 pound of fat gain. Likewise, a deficit of 3,500 calories results in 1 pound of fat loss. For the purpose of this question, we will assume that all excess calories you eat are stored as fat. Based on your answer to the question above, if your current calorie intake pattern...

In a survey to determine whether the daily caloric intake of the adolescent girls in Ahafo-Ano South district of Ashanti is less than 2000 kcal, a sample of 500 adolescent girls were randomly sampled for the study. The mean daily caloric intake from this sample was 1985 kcal, with a standard deviation of 210 kcal. Let α = 0.05. Assume you do not know the population variance; can the researchers conclude that the population mean is less than 2000 kcal...

The mean caloric intake of an adult male is 2800 with a standard deviation of 115. To verify this information, a sample of 25 men are selected and determined to have a mean caloric intake of 2950. Determine the 98% confidence interval for mean caloric intake of an adult male. Solution: Since n < 30, a t-test must be used. 2950 – qt(1.98/2,24)*115/sqrt(25) 2950 + qt(1.98/2,24)*115/sqrt(25) [2892.68, 3007.32] What is wrong with this solution?

Suppose that the mean caloric intake for Americans is 2,500 calories per day, with a standard devia- tion of 175 calories per day. Assume that caloric intakes for Americans are approximately normally distributed. (a) (3 points) Find the probability that a randomly selected American consumes more than 2,250 calories per day. (b) (3 points) Find the probability that a randomly selected American consumes at most 1,950 calo- ries per day. (c) (3 points) Find the probability that a randomly selected...
