• Let $\displaystyle {X}$  be the number of respondents out of 250 that favor Dawn Morgan for mayor. Describe the distribution of $\displaystyle {X}$  and its parameters:

~  Select an answer F T B N χ² ( $\displaystyle {n}=$ , $\displaystyle {p}=$ )

• Use the random variable notation to symbolically express the probability that at least 133 respondents favor Dawn Morgan for mayor:

Select an answer P(X>133) P(X≥133) P(X≤133) P(X<133)

• Let $\displaystyle {Y}$ be a normal variable that will be used to approximate the probability in question. Find the parameters of $\displaystyle {Y}$ (round the answers to 2 decimal places):

 $\displaystyle {Y}\sim$ Select an answer χ² N F B T ( $\displaystyle \mu=$ , $\displaystyle \sigma=$ )

• Use the random variable notation to symbolically express the approximate probability that at least 133 respondents favor Dawn Morgan for mayor:

Select an answer P(Y>133) P(Y<133)

• Use the correction for continuity:

Select an answer P(Y>132.5) P(Y>133.5) P(Y<133.5) P(Y<132.5)

• Find the probability (round the answer to 4 decimal places):
