Assume that the population distributions of ages (in years) of students at two different universities in Michigan are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics. n1=10, ¯x1=25, s21=4
n2=9, ¯x2=24x¯2=24, s22=9

Required:
a. Tell the difference in average ages of students at both universities is significant at the α=0.01 level.
b. Construct 95% confidence interval for the difference in average ages of students at both universities.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
