figure is lower. The researcher randomly selects 415 accounting companies, and through interviews determines that 303 of these companies have flexible scheduling. Using a 1% level of significance and the critical value approach, test if there is enough evidence to conclude that a significantly lower proportion of accounting companies offer employees flexible scheduling. Ensure that you clearly state your hypotheses, show ALLsteps, ALLyour working ANDinterpret your conclusion in context of this question. Let X= number of companies that offer flexible scheduling. n =415; p = 303415= 0.7301; α= 0.01 nπ=415 x 0.79=327.85 and n(1-π)=415(1-0.79)=87.15 Note that both are greater than 5, hence the normal approximation is valid. Claim: π< 0.79
