Based on a sample of 30 randomly selected years, a 90% confidence interval for the mean annual precipitation in one city isfrom 123.7 cm to 129.5 cmDetermine the margin of error involved in this confidence interval.

The annual precipitation data of a city with mean = 1000 mm and standard deviation = 200 mm. The probability that the annual precipitation will be more than 1200 mm is:Question 21Select one:a.>50%b.75%c.25 %d.<50 %

Climate researcher Dr. Taylor Johnson examined precipitation trends in this city to understand the overall climate patterns. One key finding is that the general precipitation pattern might not fully capture variations in specific seasons, as in the case of the city in question, where the average precipitation pattern _______14Mark for ReviewCross out answer choices you think are wrong.ABCWhich choice most effectively uses data from the table to illustrate the claim?Aaligned closely with precipitation in spring but differed significantly from summer.Bwas substantially lower than the precipitation during the fall each year from 2010 to 2015.Creached its highest level between 2010 and 2015, in the same season that precipitation in winter and spring reached their lowest levels.Dwas substantially lower than precipitation in winter 2010 but substantially higher than precipitation in winter 2015.

Item 9In the graph of precipitation and temperature, the area marked A has aA graph is plotted with average temperature on the horizontal axis and average precipitation on the vertical axis. The average temperature is marked in degrees Celsius from 30 to minus 10 degrees in decrements of 10 degrees. The average precipitation is marked from 0 to 400 centimeters in increments of 100 centimeters. In the graph regions from A to E are noted. The precipitation goes down as the temperature goes down. At 30 degrees average temperature, the average precipitation is 400 centimeters and it goes down steadily and the average temperature is less than 100 degrees when the average temperature is minus 10 degrees Celsius.Multiple Choicewide precipitation range and narrow temperature range.narrow precipitation and temperature range.wide precipitation and temperature range.wide temperature range and narrow precipitation range.varying temperature and narrow precipitation range.

The monthly rainfall for Adelaide and Sydney was recorded over the course of a year.Adelaide was found to have a mean monthly rainfall of 45.645.6 mm with a range of 6767 mm, while Sydney had a mean of 86.886.8 mm with a range of 5757 mm.Which city has more consistent rainfall throughout the year?

A study was commissioned to find the mean weight of the residents in certain town. The study found a confidence interval for the mean weight to be between 156 pounds and 176 pounds. What is the margin of error on the survey?
