Use inverse operations and properties of equality to isolate the variable m+31=307

otez555 [7]

ANSWER

$m = 276$

EXPLANATION

The given equation is

$m + 31 = 307$

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

$m + 31 + - 31= 307 + - 31$

Simplify;

$m +0= 307 - 31$

$m = 276$

Men women

Sample size 5 5

Mean rate 6.2 5.3

Mean diffference = $6.2-5.3=0.9$

Std error for difference = 0.25 (given)

Since we have two groups and also sample sizes are very small we can use t significant value for finding out confidence interval

df = 5+5-2 =8

t critical value for 80% two tailed = 1.397

Conf interval 80%

= $(0.9-1.397*0.25, 0.9+1.397*0.25)\\= (0.55525, 1.24475)$
