11. In order to estimate the mean amount of time computer users spend on the internet 10 each month, how many computer users must be surveyed in order to be 95% confident that your sample mean is within 11 minutes of the population mean? Assume that the standard deviation of the population of monthly time spent on the internet is 201 min. The minimum sample size required is computer users. What is a major obstacle to getting a good estimate of the population mean? O A. There may not be 1,283 computer users to survey. O B. It is difficult to precisely measure the amount of time spent on the internet, invalidating some data values. O C. The data does not provide information on what the computer users did while on the internet. O D. There are no obstacles to getting a good estimate of the population mean.
Suppose 140 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean 85 g and standard deviation 2 g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 81 g and 89 g. The number of students reporting readings between 81 g and 89 g is (Round to the nearest whole number as needed.)
The ages of a group of 134 randomly selected adult females have a standard deviation of 18.2 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 18.2 years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students? Assume that we want 98% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is 7194 . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. No, because there is no age difference between the population of statistics students and the general population. B.…
Assume blood-glucose levels in a population of adult women are approximately normally distributed with mean 90 mg/dL and standard deviation 13 mg/dL. - Suppose the "abnormal range" were defined to be glucose levels outside of 1 standard deviation of the mean (i.e., either at least 1 standard deviation above the mean, or at least 1 standard deviation below mean). What percentage of individuals would be called "abnormal" and need to be retested?
