There is data representing the daily working hours of 5 employees of "horizon bakery cafe". A manager would like to determine that their recommended working hours are 8 on average. ,find the appropriate t-critical value at alpha = 0.05(

Please note, the values in the table in the text are given as (1 - alpha). Some other tables you might find are given as (alpha)

So for alpha = 0.05, in this table you would use the column for 0.95. For alpha = 0.01, you would use the column for 0.99

Another consideration - these tables give 1-tailed data. So for a two tailed test you need to use (alpha/2).

So for this study, 2-tailed alpha = 0.05 you would use the column labeled 0.975

Is the data result in a statistically significant t-test? Why or why not?

Employee	working hours
1	7.8
2	5.5
3	4.6
