1) A distribution with μ = 15 and s = 3 is being standardized so that the new mean and standard deviation will be µ = 25 and s=5. When the distribution is standardized, what value will be obtained for a score of X = 8 from the original distribution? 2) A population of scores has μ = 24. In this population, a score of X= 14 corresponds to z = -1.35. What is the population standard deviation? 3) What proportion of scores are between 18 and 25, based on the following sample: 18 23 22 22 13 28 15 18 21 14 12 17

how to calculate standard deviation

Approximate the population mean and standard deviation of age for males. By the way, we are finding the midpoints by adding vertically by the first numbers before the hypens in the age column, and then dividing by 2 (ex: 0+10/2=5, 10+20/2=15, 20+30/2=25)

How to find Distribution while given Estimator in point estimator

What distribution is used in this chapter to make inferences for two population standard deviations?

If a distribution has a mean of 46 and a standard deviation of 1, what value would be -2 standard deviations from the mean?

Az-score of z = +1.00 indicates a position in a distribution Above the mean by 1 point. Above the mean by a distance equal to 1 standard deviation. Below the mean by 1 point. Below the mean by a distance equal to 1 standard deviation.

Question 13 A particular fruit's weights are normally distributed, with a mean of 405 grams and a standard deviation of 19 grams. The heaviest 5% of fruits weigh more than how many grams? Give your answer to the nearest gram.

If a distribution has a mean of 50 and a standard deviation of 5, what value would be -1 standard deviation from the mean?

What is an Epidemic Curve? An epi curve is a visual display of the onset of illness among cases associated with an outbreak. You can learn a lot about an outbreak from an epi curve, such as The outbreak's time trend, that is, the distribution of cases over time Outliers, that is, cases that stand apart from the overall pattern A general sense of the outbreak's magnitude Inferences about the outbreak's pattern of spread The most likely time period of exposure (Source: Center for Disease Control, US) Here you will compare epi curves from three countries- South Korea, Italy, and the USA.   The table below shows the number of active cases in South Korea, Italy, and the USA.  The data is shown in two-day intervals starting on February 15 and ending March 17 (note March 17 is a one-day interval).    Cut and paste the data table into Excel or Google Sheets.  Make and X-Y Scatter Plot (with connecting lines).  This will be your epidemic curve.     South Korea Italy USA…
