    Answer:

    0.8333

    Step-by-step explanation:

    Given that a group of statistics students conducted a random sample of 64 students at their college.

    Their findings showed that the sampled students studied an average of 15 hours per week with a standard deviation of 5 hours

    i.e we have

    sample size = n=64

    Standard deviation of sample s = 5

    By central limit theorem we have sample mean will follow a normal distribution with mean = sample mean and std error = std deviation /square root of n.

    Substitute the values to get

    Standard error of means =\frac{5}{\sqrt{64} } \\=0.8333
