<h2>˜”*°•.˜”*°• Question •°*”˜.•°*”˜</h2>

<em>The library had 102 shelves of books. Each shelf had 14 books. Librarians checked out 807 books to students. how many books does the library have remaining?</em>

<em />

<h2>˜”*°•.˜”*°• Answer •°*”˜.•°*”˜</h2>

627 Books

<h2> </h2><h2>˜”*°•.˜”*°• Explanation •°*”˜.•°*”˜</h2>

Let's go through this together.

First, let's figure out how many books are in the library in all

We'll multiply s times b

- S being the shelves

- B being the books per shelf.

102(14) = 1,428

So, there are 1,428 books in the library.

We also know that 801 of the 1,428 books were checked out.

Let's subtract the total number of books by the amount checked out.

1,428 - 801 = 627

Therefore, there are 627 books still in the library after checkout.

Leviafan [203]

Answer:

a. H0:μ1≥μ2

Ha:μ1<μ2

b. t=-3.076

c. Rejection region=[tcalculated<−1.717]

Reject H0

Step-by-step explanation:

a)

As the score for group 1 is lower than group 2,

Null hypothesis: H0:μ1≥μ2

Alternative hypothesis: H1:μ1<μ2

b) t test statistic for equal variances

t=(xbar1-xbar2)-(μ1-μ2)/sqrt[{1/n1+1/n2}*{((n1-1)s1²+(n2-1)s2²)/n1+n2-2}

t=63.3-70.2/sqrt[{1/11+1/13}*{((11-1)3.7²+(13-1)6.6²)/11+13-2}

t=-6.9/sqrt[{0.091+0.077}{136.9+522.72/22}]

t=-3.076

c. α=0.05, df=22

t(0.05,22)=-1.717

The rejection region is t calculated<t critical value

t<-1.717

We can see that the calculated value of t-statistic falls in rejection region and so we reject the null hypothesis at 5% significance level.
