Answer:

85200 minutes

Step-by-step explanation:

2500-1080=1420

1420 Is the number of hours the light burns during night. Multiply this by 60 to find the number of minutes.

1420×60=85,200 minutes

Find the t-value such that the area in the right tail is 0.005 with 28 degrees of freedom.
klasskru [66]

Answer:

t = 3.673900

Step-by-step explanation:

Given

df = 28 -- degree of freedom

Area = 0.005

Required

Determine the t-value

The given parameters can be illustrated as follows:

P(T > t) = \alpha

Where

\alpha = 0.005

So, we have:

P(T>t) = 0.005

To solve further, we make use of the attached the student's t distribution table.

From the attached table,

The t-value is given at the row with df = 28 and \alpha = 0.005 is 3.673900

Hence, t = 3.673900
