Answer:
95% confidence interval for the whole-brain volume of autistic toddlers is between a lower limit of 1185.056 ml and an upper limit of 1374.944 ml.
Explanation:
Confidence interval = mean + or - Error margin (E)
mean = 1280 ml
sd = 230 ml
n = 25
degree of freedom = n - 1 = 25 - 1 = 24
confidence level = 95%
t-value corresponding to 24 degrees of freedom and 95% confidence level is 2.064
E = t×sd/√n = 2.064×230/√25 = 94.944 ml
Lower limit = mean - E = 1280 - 94.944 = 1185.056 ml
Upper limit = mean + E = 1280 + 94.944 = 1374.944 ml
95% confidence interval is between 1185.056 ml and 1374.944 ml.
I think the answer is fewer because once you are dealing with disease and other health problems, more resources are needed (which are usually more expensive).
The answer to the qustion is a lack of oxygen.
I think you would die because its basically drugging yourself
