    Answer:  0.0971

    Step-by-step explanation:

    Given : Sample size : n=26

    The percent of people are afraid of flying =43\%

    Thus the proportion of people are afraid of flying P=0.43

    We know that the formula to find the standard deviation of the distribution of sample proportions is given by :-

    \text{S.E.}=\sqrt{\dfrac{P(1-P)}{n}}\\\\\Rightarrow\text{S.E.}=\sqrt{\dfrac{0.43(1-0.43)}{26}}\\\\\Rightarrow\ \text{S.E.}=0.0970923430396\approx0.0971

    Hence, the standard deviation of the distribution of sample proportions = 0.0971
