nypotheSIS fest) Use the following historical data for the annual average temperature records for New York City, USA to answer the following questions. For each year, the data value is calculated by taking the average of the daily high temperature readings from every day of that year, observed in a specific location, e.g., Central Park for New York and Observatory Hill for Sydney. The data are sorted by year in ascending order. For your convenience, temperatures have been converted to the Fahrenheit scale.

Transcribed Image Text:Project-3: Historical Temperature Trends (Hypothesis test)
Use the following historical data for the annual average temperature records for New York City,
USA to answer the following questions. For each year, the data value is calculated by taking the
average of the daily high temperature readings from every day of that year, observed in a specific
location, e.g., Central Park for New York and Observatory Hill for Sydney. The data are sorted by
year in ascending order. For your convenience, temperatures have been converted to the Fahrenheit
scale. You can find the data and the original data sources at https://lagcc-
cuny.digication.com/project data/Temperature Trends.)
For your convenience the data files are attached along with the assignment.
Q1) Let be the average temperature of the world for the past 100 years from 1914-2013 measured
in Fahrenheits. Conduct the hypothesis test using the t-distribution to test at 5% level of
significance if the annual average temperature of New York City has increased over the
years. Write your conclusion from the results you obtained. (Hint: Compute the average
temperature () and the standard deviation (s) from the given data for the last 25 years.)
