Answer:

Step-by-step explanation:

let the numbers be x and y and x>y

x-y=3

x+y=27

add

2x=30

x=30/2=15

15+y=27

y=27-15=12

Answer:

The 95% confidence interval for the mean score is:

$\mu$ ∈ $(67.73,\ \ 84.67)$

Step-by-step explanation:

We want to estimate the population mean, that is, the average score of all the subjects.

An estimator for the population mean μ is ${\overline {x}}$

Since the sample size is $27$ then we use the statistic $t_{\frac{\alpha}{2}}$ with $27-1 = 26$ degrees of freedom

The confidence interval for the mean is:

$({\displaystyle {\overline {x}}} + t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}},\ \ {\displaystyle {\overline {x}}} - t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}})$

Where

${\displaystyle {\overline {x}}}=76.2$ is the average score of the sample

$S=21.4$ is the standard deviation of the sample

$n= 27$ is the sample size

$t_{\frac{\alpha}{2}} = 2.056$ for a confidence level of 95% and 26 degrees of freedom

Then confidence interval is

$(76.2 + 2.056\frac{21.4}{\sqrt{27}},\ \ {76.2 - 2.056\frac{21.4}{\sqrt{27}})$

$(76.2 + 8.467,\ \ 76.2 - 8.467)$

$\mu$ ∈ $(67.73,\ \ 84.67)$
