The average age at which adolescent girls reach their adult height is 16 years. Suppose you have a sample of 27 adolescent girls
abruzzese [7]

Answer:

a) t-statistic  t = 0.9532

b) The standard error  S.E = 1.2

c) The new  t-statistic = 1.95

d)  The new estimated standard error =0.666

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the mean of the Population = 16

The sample size n=27

The mean of the sample = 17.1

Given that the variance of the sample (S²) = 36.0

The standard deviation of the sample (S) = √36 = 6

Test statistic

  t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }

 t = \frac{17.1 -16}{\frac{6}{\sqrt{27} } }

t = 0.9532

b)

   The standard error is defined by

  S.E = \frac{S.D}{\sqrt{n} } = \frac{6}{\sqrt{27} } =1.154

<u><em>Step(ii):-  </em></u>

c) given that the sample size n = 81

Test statistic

 t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }

 t = \frac{17.1 -16}{\frac{6}{\sqrt{81} } }

t = 1.65

d)

The new standard error is defined by

  S.E = \frac{S.D}{\sqrt{n} } = \frac{6}{\sqrt{81} } = 0.66

Janae's savings account has $50 on September 19. If she plans to save $5 every day, how much money will Janae have in her saving
Akimi4 [234]

Janae will have $ 95 in her account after 10 days.

<h3>What is an Arithmetic Progression?</h3>

A sequence of numbers that has a fixed common difference between any two consecutive numbers is called an arithmetic progression (A.P.)

Given,

Amount in Janae's account = $ 50

Amount she wishes to save for 10 days = $ 5

This scenario models an arithmetic progression(A.P)

In an A.P,

a _n = a + (n-1)d

where a _n = nth term, a is the first term, n is the no. of terms and d is the common difference.

In this question, a = 50, n = 10, d = 5 and we have to find out a _n

Therefore, a _n = 50 + (10-1)x5

                         = 50 + 45 = 95

Answer:- Janae will have $ 95 in her account after 10 days.
