You want to estimate the proportion of kids between the ages of 12 and 15 who have tried marijuana. You take a random sample of 130 Maryland students and find that 23% of the sample report having tried marijuana. Last year, the known population of 12-15 year olds who had ever tried marijuana was 29%. Test the alternative hypothesis that the population proportion of Maryland students who have smoked marijuana is different than 29%. Use an alpha level of 0.01. What is your alternative hypothesis? $$H_1: p \neq 0.29$$ $$H_1: p \neq 0.23$$ $$H_1: p < 0.23$$ $$H_1: p < 0.29$$

A bicycle wheel is in the shape of a hoop (ignore the mass of the spokes). It has a mass of 1.88 kg and a radius of 0.300 m . It rolls without slipping at a speed of \( 3.78 \frac{\mathrm{~m}}{\mathrm{~s}} \). The total kinetic energy of the wheel is \( \qquad \) J. Note: The moment of inertia of a hoop around an axis through its center is given in tables as \( I_{\text {hoop }}=M R^{2} \).

Schmid is a 27-year-old G1 P1 whose pregnancy was complicated by gestational diabetes with fetal macrosomia and polyhydramnios. Post-birth, Smith developed uterine atony, which was initially unresponsive to fundal massage, medical therapy, and conservative non-surgical attempts to control the hemorrhage. Her quantitative blood loss was 2,150 mL with a blood pressure of 80/40 and a pulse of 130. The decision is made to proceed to emergency hysterectomy. What orders can you anticipate next? Please select two answers: activate the massive transfusion protocol, obtain a blood type and crossmatch, or administer crystalloids three times the patient's estimated blood volume.
