Assume that a researcher wants to estimate the proportion of "A" grade scorers in
STAT101 course for the population of SEU
students in 2020. Assume also that the
proportion of "A" grade scorers in 2020 is not
known. How many SEU students must be
surveyed from STAT101 course in order to be
90% confident and the margin of error should
not exceed two percentage points? (Given za/ 2 = 1.64).

1-1821
2-1781
3- 1618
4-1681

answer: the equation matches the regression

step-by-step explanation:

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
