Step 1
- Sum of reaction times = \(0.018 + 0.012 + 0.015 + 0.008 + 0.01 = 0.063\) seconds. - Number of trials = 5. - Average reaction time = \( \frac{0.063}{5} = 0.0126\) seconds. Show more…

In measuring reaction time, a psychologist estimates that the standard deviation is 0.05 seconds. How large a sample of measurements must be taken in order to be (a) 95% , (b) 99% and (c) 50% confident that the error in his estimate of mean reaction time will not exceed 0.08 second? (Hint: X̄ ± z_c σ/∑n z_c 99%=2.58 , z_c 95%=1.96 z_c 50%=0.6745 z table. X̄ is nearly normal distribute.)

In a psychological testing experiment, 100 subjects are selected randomly and their reaction time, in seconds, to a particular stimulus is measured. Past experience suggests that the population standard deviation in reaction times to these types of stimuli is 4 seconds and that the distribution of reaction times is approximately normal. The (sample) average time for the subjects is 16 seconds. Give an upper 97.5% bound (one-sided) for the mean reaction time. Write your answer with 3 digits after the decimal point. For example, 0.782 or 0.352.
