A lumber company is making doors that are 2058.0 millimeters tall. If the doors are too short they cannot be used. A sample of 7 is made, and it is found that they have a mean of 2046.0 millimeters with a variance of 625.0. A level of significance of 0.1 will be used to determine if the doors are too short. Assume the population distribution is approximately normal. a. State the null and alternative hypotheses. b. Calculate the test statistic. c. Find the P-Value. d. Determine whether to reject or fail to reject the null. e. Write a statement explaining the meaning of your conclusion in part d.

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
