The mean and median scores of a recent Stat 111 exam were close to 68%. The instructor decided not to count one score of zero that was from an absent student to get a better representation of the class average and then recalculated the new mean and median. a) Will the new mean increase, decrease or remain about the same? Explain.
b) Will the new median increase, decrease or remain about the same? Explain.
c) Will the overall range increase, decrease or remain about the same? Explain.
d) Will the IQR increase, decrease or remain about the same? Explain.
The mean and median

lol we need to see what the question is asking about

step-by-step explanation:

it is a secret for it not to be compromised sorry

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

b.
