A random sample of n individuals were selected. A 95% confidence interval ($52,000 to $70,000) was constructed using the sample results.

Which of the following statement(s) is/are true? (Can choose answer more than 1)

If all possible samples of size n were drawn from this population, about 95% of the population means would fall in the interval ($52,000 to $70,000).

We do not know for sure whether the population mean is in the interval $52,000 and $70,000.

If all possible samples of size n were drawn from this population, 95% of the intervals established by the above method would contain the population mean.

If all possible samples of size n were drawn from this population, about 95% of the sample means would fall in the interval ($52,000 to $70,000).

A random sample of 100 stores from a large garden supply chain was selected to determine the average number of lawnmowers sold at an end-of-season clearance sale. A 95% confidence interval was calculated to be 5.62 < μ < 6.38 based on the sample statistics. The confidence interval may be interpreted as follows. A. 95% of the stores have sold between 5.62 and 6.38 lawnmowers on average. B. There is a 95% probability that the sample mean number of lawnmowers...

A random sample of 180 residents of Milpitas, CA, was surveyed, and a 95% confidence interval was constructed in order to estimate the average amount of time it takes for residents of Milpitas to commute to work each day. The interval ended up being from 10.25 minutes to 65.74 minutes. What would be a correct interpretation of this interval?   A. We are 95% confident that if we randomly select one individual from Milpitas, that person will take between 10.25 minutes...
