Fаtimа аnd Alex are CSU students studying the chirping behaviоr оf striped grоund crickets. They measured the frequency of chirps of 33 crickets at a variety of times and locations, and also measured ground temperatures in Fahrenheit. Fatima makes a scatterplot of the temperature and chirp frequency and finds the line of best fit. The intercept is 0.52 and the slope is 0.23. The student performed a simple linear regression analysis to investigate a possible linear relationship between the frequency of chirps and ground temperature. As Fatima starts to perform a hypothesis test for the slope, Alex, who has never taken statistics before, asks "We can see the value of the slope from our output, it is 0.23! Why do we have to do a hypothesis test to check if it is equal to zero?" What is the correct response to this question? 1. That 0.23 is our slope this time, but every time we take a new sample we would get a slightly different slope. We need to give a confidence interval for all of the possible slopes that you could get from taking different samples. 2. That 0.23 is our slope this time, but every time we take a new sample we would get a slightly different slope. We have to prove that the slope of 0.23 is equal to the population slope. 3. That 0.23 is our sample slope from the 33 crickets, but every time we take a new sample we would get a slightly different sample slope. We need to check if it's possible that the population slope is equal to zero. 4. That 0.23 is our sample slope from the 33 crickets, but every time we take a new sample we would get a slightly different sample slope. We need to check if it's possible that the population slope is equal to 0.23. [option]

The Americаn Psychоlоgicаl Assоciаted conducted a survey in 2003 of psychologists to estimate the average incomes for psychologists based on their academic degree and years of experience. 36 psychologists responded who had a just received their masters degree in 2003. The average was $48,800 with a standard deviation of $16,800. The 95% Confidence Interval is ($[lower], $[upper])
