Assume the birth weights at a local hospital have a normal distribution with a mean of 110 oz and a standard deviation of 15 oz. Draw a normal curve and label the mean and each value which is one, two, or three standard deviations above the mean. Then label each value which is one, two, or three standard deviations below the mean.

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.

Use the mean and standard deviation formula for a Uniform Distribution for our population distribution. Take the mean and standard deviation from your population distribution to find the mean and standard error of your sampling distribution. Don’t forget to label your axes and do not forget to write out your calculator command. Don’t forget the units on your percentile. Every statistic has the same units as your variable. All this information that is above goes with the image attached Please please answer everything please at least try to answer everything please I would really appreciate it thank you

Her annual income is 5 standard deviations higher than the mean Her annual income is 5 dollars higher than the mean Her annual income is 5 points higher than the mean The mean of the sample is 5 thousands dollars higher than Robin’s income
A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1458 and the standard deviation was 312. The test scores of four students selected at random are 1860, 1220, 2150, and 1340. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1860 is (Round to two decimal plaes as needed.)
Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $227 with a standard deviation of $69. Random samples of size 31 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is nothing.
