Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting for, either north high school or south high school. of the surveyed adults, 96 said they were rooting for north high while the rest said they were rooting for south high. eric wants to determine if this is evidence that more than half the adults in this city will root for north high school. which of the following is the correct alternative hypothesis?
a. h0? : p? > 0.5 where p? = the proportion rooting for north high school
b. h0? : p? = 0.64 where p? = the proportion rooting for north high school
c. h0? : p? = 0.5 where p? = the proportion rooting for north high school

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
