The mean cholesterol levels of women age 45-59 in Ghana, Nigeria, and Seychelles is 5.1 mmol/l and the standard deviation is 1.0 mmol/l. Assume that cholesterol levels are normally distributed and a random sample of 21 women are selected.
It is possible with rounding for a probability to be 0.0000.
The questions are in the picture thank you
Extracted text: g) Find the probability that the sample mean cholesterol level of the 21 randomly selected women age 45-59 in Ghana, Nigeria, and Seychelles is less than 5 mmol/l. Round final answer to 4 decimal places. DO NOT use the rounded standard deviation from part e in this computation. Use the EXACT value of the standard deviation with the square root. h) Find the probability that the sample mean cholesterol level of the 21 randomly selected women age 45-59 in Ghana, Nigeria, and Seychelles is more than 5.44 mmol/I. Round final answer to 4 decimal places. DO NOT use the rounded standard deviation from part e in this computation. Use the EXACT value of the standard deviation with the square root. i) Is a mean cholesterol level of 5.44 mmol/l unusually high for 21 randomly selected women age 45-59 in Ghana, Nigeria, and Seychelles? Select an answer j) If you found a mean cholesterol level for a sample of 21 women age 45-59 in Ghana, Nigeria, and Seychelles as high as 5.44 mmol/l, what might you conclude? Select an answer Select an answer There is evidence that the mean cholesterol level of all women age 45-59 in Ghana, Nigeria, and Seychelles may now be higher than 5.1 mmol/l There is no evidence that the mean cholesterol level of all women age 45-59 in Ghana, Nigeria, and Seychelles has changed from 5.1 mmol/ There is evidence that the mean cholesterol level of all women age 45-59 in Ghana, Nigeria, and Seychelles may now be lower than 5.1 mmol/i Submit Question
