What I need to know:

To describe how well this novel strain of rat performs on the delayed matching-to-sample task, calculate the lower and upper latencies that encompass 95% percent of latencies expected from this novel strain of rat - i.e., find the z-scores associated with the area of the middle 95% of scores from the standard normal distribution and then back-transform the lower and upper z-scores associated with this area into latencies (hint: you will need to use the population mean () & standard deviation () calculated in 2c & 2d)

INFO YOU'LL NEED TO CALCULATE THE QUESTION ABOVE.

DATA:

Subject ID	Latency (s)		Subject ID	Latency (s)
110	8		111	8
210	14		211	14
310	14		311	5
410	16		411	14
510	6		511	7
610	11		611	12
710	8		711	17
810	12		811	10

Mean: 11

Standard Deviation: 3.57
