Question

Actual times (in seconds) recorded when statistics students participated in an experiment to test their ability to determine when one minute (60 seconds) had passed are shown below. Find the mean, median, and mode of the listed numbers. 55 50 74 61 67 60 47 47

Answer #1

arranging the data in increasing order:-

47, 47, 50, 55, 60, 61 ,67 ,74

sample size(n) = 8

**the mean
be:-**

**57.625**

**the median
be:-**

[ as n=8 is even]

= **57.5**

**the mode
be:-**

= the value with the highest frequency

= **47** [ as it has
occurred 2 times ]

Randomly selected students participated in an experiment to test
their ability to determine when one minute (or sixty seconds) has
passed. Forty students yielded a sample mean of 59.7 seconds.
Assuming that sigma =10.1 seconds, construct and interpret a 90%
confidence interval estimate of the population mean of all
students.
What is the 90% confidence interval for the population mean
μ?

Randomly selected students participated in an experiment to test
their ability to determine when one minute (or sixty seconds) has
passed. Forty students yielded a sample mean of 62.4 seconds.
Assuming that σ=8.5 seconds, construct and interpret a 99%
confidence interval estimate of the population mean of all
students.
What is the 99% confidence interval for the population mean
μ?

Time perception. Randomly selected college students participated
in an experiment that tested their ability to determine the course
of 1 minute (or 60 seconds). Forty students produced a sample mean
of 58.3 seconds. Assuming that the standard deviation is 9.5
seconds, use a significance level of 0.05 to test the assertion
that the population mean is less than 60 seconds.

A random sampling of 30 students are selected. The number of
times they eat at a campus are shown in the following.
