Temperatures in Chicago and San Francisco The maximum daily temperature (degree

Question

Temperatures in Chicago and San Francisco The maximum daily temperature (degree F) for Chicago and San Francisco during the part ial month of August 2009 are given in the data arrays below (data from the U.S. National Oceanic and Atmospheric Administration). ChiTemp = [75 79 86 80 79 81 73 89 91 86 81 82 86 88 89 00 82 84 81 79 73 69] SFTemp = (69 68 70 73 72 71 69 76 85 87 74 81 76 68 79 75 68 68 73 72 79 68) Construct script files in MAT LAB (c) for each of the exercises. Control and detail your output using fprintf using no decimal values modeling each execution output below. Calculate the average temperature for the month in each city. .Name your script file tempAnalysisA.m. As an example, see the following execution output: How many days was the temperature above the average in each city? Name your script file tempAnalysisB.m. As an example, see the following execution output: How many days was the temperature in San Francisco lower than the temperature in Chicago? Name your script file tempAnalysisC.m.

Explanation / Answer

% all the three functions are as follows.

% tempAnalysisA

ChiTemp=[75 79 86 86 79 81 73 89 91 80 81 82 86 88 89 90 82 84 81 79 73 69];
SFTemp=[69 68 70 73 72 71 69 76 85 87 74 84 76 68 79 75 68 68 73 72 79 68];
  
ChiAvg=mean(ChiTemp);
SFAvg=mean(SFTemp);
  
fprintf('Chicago average temperature: %f Degrees ',ChiAvg);
fprintf('San Francisco average temperature: %f Degrees ',SFAvg);
