Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

x_1=17.500\\s_1=3.529\\n_1=12

Logged:

x_2=13.667\\ s_2=4.500\\n_2=9\\

formula of std error:

\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}

                =\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133

Point differential estimation =x_1-x _2

                                              = 17.500-13.667\\=3.833

For 90 percent t= 1.860 Cl & 8 df  

error of margin E = t\times \ std \ error

                             = 1.860 \times 1.8133\\= 3.373

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)

A cup and saucer cost $3.10 at the local store. The cup costs $2.00 more than the saucer. How much does each cost?
AlekseyPX

Answer: cup is $2.55

Saucer $0.55

Step-by-step explanation:

Cost of cup and saucer is $3.10

Let the cup be x

And saucer be y

I.e

X+y= 3.10......equation 1

Cup which is X is $2 more than the saucer

I.e x=2+y......equation 2

Substitute for X in equation 1

(2+y)+y=3.10

2+2y=3.10

2y=3.10-2

2y=1.10

Y=1.10/2

Y=$0.55

Substitute for y in equation 2

X=2+y

X=2+0.55

X=$2.55

Therefore

The cup is $2.55

The saucer is $0.55
