    An astronomer is testing the claim that the mean brightness of a certain star is now more than 30 units. She is able to get 6 readings on the star during her experiment as shown in the table. Using α = 0.01, does this indicate a new mean brightness of more than 30?

    DATA

    Reading Brightness

    1 29
    2 29
    3 29
    4 31
    5 32
    6 34

    Assume that such readings are normally distributed.

    PS: PLEASE SHOW ALL WORK AND EXPLAIN IN BASIC, BASIC TERMS. ALSO, I REQUEST FOR THE SAME TA (CHANGPING WANG, MA)

    Sorry I 'M NOT SURE IF THIS IS A TWO-SAMPLE t TEST!
