Question

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.5 years with a standard deviation of 0.7 years. Step 2 of 2 : If a sampling distribution is created using samples of the ages at which 43 children begin reading, what would be the standard deviation of the sampling distribution of sample means

    Answer:

    S.E = 0.108

    Step-by-step explanation:

    From the question we are told that:

    Mean age \=x=5.5

    standard deviation \sigma= 0.7 years.

    Sample size n=43

    Generally the equation for Standard error is mathematically given by

    S.E= \sigma \bar x

    S.E= \frac{\sigma}{\sqrt n}

    S.E= \frac{0.7}{\sqrt 43}

    S.E = 0.108
