A researcher calculated average sleep hours per night for a random sample of (n=59

59) students. The researcher hypothesised that a healthy person is expected to sleep7.5

7.5hours per night (0=7.5). The sample mean is equal to8 hours and the sample variance is equal to0.88hours.

Research Question: Is the average hours of sleep equal to hypothesised hours of sleep per night?

Answer the following questions by choosing the most correct option or typing the answer:

1) The most appropriate test for these data is:

a) A one sample t test

b) A two sample t test

For the remaining questions you may assume that any relevant assumptions have been met.

2) The absolute value of the test statistic is equal to (3dp)

3) The degrees of freedom is equal to (integer)

4) The p-value is larger than 0.05? TRUE or FALSE

5) The test shows that the average hours of sleep was

a) significantly different than hypothesised value (lower)

b) significantly different than hypothesised value (greater)

c) not significantly different than hypothesised value
