    Question Null and Alternate Hypothesis

    I have question on one sample z test. the sugar contents in biscuits are given for 40 packets.
    The question is to "Perform an appropriate hypothesis test to validate the manufacturers claim that the biscuit contains no more than 1.5g sugar in it."

    How to write the null and alternate hypothesis?

    IS IT

    H​0 :mu=1.5
    H1:mu> 1.5OR

    H​0 :mu=1.5
    H1:mu< 1.5

    Thanks in advance.

    "No more than 1.5 g sugar" means mu<1.5. So the second one is correct.
