Investigation: Strawberry Consumption

Blueberry consumption has increased dramatically in the last decade, but strawberries are still the number one berry in the United States. Annual strawberry consumption in the US is normally distributed with a mean of 7 lbs per person in 2018. Suppose that you want to decide whether last year's mean strawberry consumption has increased from the mean in 2018.

An excel table on blackboard provides last year's strawberry consumption, in pounds, for 21 randomly selected Americans. Follow the instructions below to upload this table and analyze the data to decide if the mean consumption of strawberries has increased since 2018.

Stat Crunch Portion of the lab:

1. Upload Report Data

> Go to Blackboard/StatCrunch/Report 2 and copy the Strawberry Data S22.xlsx file to your computer.

> Enter Mylab Statistics. Click on StatCrunch. Then click on "StatCrunch website"

> Under "Data" click on "Upload Data"

➤ Drag the Strawberry F22.xlsx file to the "Drag file here" area.

Keep check mark on "First line as column name". Click Upload.

2. The default in StatCrunch is 8 significant digits for all results. We want to change this to 4. Click the drop-down menu for Edit and select "Display Precision". Under Results display choose 4 digits.

3. Use Stat Crunch to produce a table of descriptive summary statistics containing the mean, median (Q2), standard deviation, range, min, max, Q1, Q3, and IQR of the Grade Data.

a. In Stat Crunch on the top row click on "Stat"=> "Summary Stats" => "Columns"

b. Under Select Column(s) (Ctrl-click) on each to select "Strawberry Consumption".

c. Under Statistics (Ctrl-click) on each to select: Mean, Std. dev., Median, Range, Min, Max, Q1, Q3, IQR.

d. Compute!

A table will appear with descriptive statistics for Strawberry Consumption. Remember the median is Q2.

4. Produce a 95% confidence interval for the population mean strawberry consumption. a. In Stat Crunch on the top row click on "Stat"=>"T Stats" => "One Sample" => "With Data"

b. Under Select Column(s) select "Strawberry Consumption".

c. Under Perform: select "Confidence Interval for u". Level "95%"

d. Under Optional graphs and tables: select "Confidence interval plot", Compute!
