MATLAB User Defined Functions and Relational Operators

Problem $2-$ Use the MATLAB find function with appropriate relational operators to answer the following questions about the temperatures of a hot tub within a full $24$ hour period.

Use the $f$ ind function to find the index numbers of the temperatures that exceed $104F.$

Use the length function to find how many temperatures are above $104F.$

Determine what times the temperature exceeded $104F.$

Determine how many times the temperature was less than $103F.$

What times were the temperatures below $103F?$

Determine what times the temperature was within the range $102F$ to $104F$ Inclusive.

What is the maximum temperature and what time did it occur?

What is the minimum temperature and what time did it occur?

What is the average temperature?

What is the standard deviation of the temperature data?

What percentage of the temperature data is $103F$ or less?

What percentage of the data is in the range of mean $+-$ standard deviation?
