a$.$ Use IDEA to determine the necessary sample size, given the preceding parameters. b$.$ Assume that your audit team has decided to increase their reliance on internal control and permit a corresponding increase in the risk of incorrect acceptance from $10$ percent to $15$ percent, which maintains overall audit risk at the same level. What is the necessary sample size, holding all other factors constant? c$.$ Assume that your audit team has decided to reduce the level of tolerable misstatement from $\backslash (\backslash$$ $311,711\backslash )$ to $\backslash (\backslash$$ $233,783\backslash )($or $6$ percent of the recorded balance of the transactions$).$ What is the necessary sample size, holding all other factors constant? d$.$ Assume that based on additional controls implemented by ELM, your audit team has decided to reduce the expected misstatement from $\backslash (\backslash$$ $77,928\backslash )$ to $\backslash (\backslash$$ $19,482\backslash )(0\mathrm{.}5$ percent of the recorded balance of the transactions$).$ What is the necessary sample size, holding all other factors constant?
