In this scenario, what is the test statistic?

• A psychologist would like to test the claim thatthe average length of time sensory information is stored as sensory memory is different than0.3
• seconds.
• Sample size=37
• adults
• Sample mean=0.33
• seconds
• From past data, it is known that the population standard deviation is0.09
• seconds.
• Calculate the test statisticusing the formula:
• z
• 0
• =x
• 0
• n
• where:
• x
• = sample mean
• = population standard deviation,
• n
• = sample size, and
• 0
• = population mean under the null hypothesis.
• Round your answer to2
• decimal places.
