\begin{tabular}{l}\hline Skill 2: Statistics - finding the mean \\ \hline Find the mean of these heights \( (\mathrm{cm}) \) : \\ \( 116.0 \quad 125.8,117.1,117.2,120.0,123.9,138.0,132.4,122.5,156.2,138.3,139.0,139.7 \)\end{tabular}

Factor the higher degree polynomial. Select "Prime" If the polynomial cannot be factored. \[ 15 t^{4}+t^{2}-2 \]

(a) \( 0 . \overline{12}= \)

Factor completely. Be sure to factor out the GCF first. Select "Prime" If the polynomial cannot be factored. \[ 129 y+45+24 y^{2} \] \( 129 y+45+24 y^{2}=\square \)

According to the U.S. government, the per capita consumption of bottled water by Americans has a mean of 24.2 gallons per year and a standard deviation of 2.9 gallons per year. A marketing company is researching current trends in bottled water consumption. They select a random sample of 38 Americans bottled water consumption per year and find the mean consumption to be 24.9 gallons per year. Can the Central Limit Theorem be applied to this situation? A) No, because the sample is not large enough. (B) Yes, because the parent population is normally distributed. C) Yes, because the sample is large enough. (D) No, because the parent population is not normally distributed. (E) The Central Limit Theorem is not needed because the focus is on individual bottled water consumption, not sample
