1)A sample of 17 patients in a hospital had these hemoglobin readings (grams):
112 120 98 55 71 35 99 124 64
150 150 55 100 132 20 70 93
Find a 95% confidence interval for the hemoglobin reading for all the patients in the hospital.
2)A sample of 500 nursing applications included 60 from men. Find the 90% confidence interval for the true proportion of men who applied to the nursing program.
3)Average undergraduate cost for tuition, fees, room, and board for all institutions last year was $19,410. A random sample of costs this year for 40 institutions of higher learning indicated that the sample mean was $22,098, and the sample standard deviation was $6050. At the α=0.01, is there sufficient evidence to conclude that the cost of attendance has increased?

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function. how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
