Answer:

The percent of increase is 30%

Step-by-step explanation:

These are my solution's

Increase = New Number - Original Number. ↓

1300 - 1000 = 300

Next,

% increase = Increase ÷ Original Number × 100.↓

300 divided by 1000 = 0.3 x 100 = 30%

Please mark as a brainiest if my answer was helpful.

Thx UwU

At the Foremost State Bank the average savings account balance in 2012 was $1900. A random sample of 45 savings account balanes
lakkis [162]

Answer:

The calculated  |t| = |-26.517|=26.517 > 2.326 at 0.01 level of significance

Null hypothesis is rejected at 0.01 level of significance

There is difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012

Step-by-step explanation:

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

Mean of the Population = 1900

Given random sample size 'n' =  45

Mean of the sample x⁻ = 1000

Standard deviation of the sample = 225

<u><em>Null Hypothesis</em></u>:-

There is no difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012.

<u><em>Alternative Hypothesis</em></u> :-

There is difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012

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

Test statistic

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

        t = \frac{1000-1900 }{\frac{225}{\sqrt{45} } }

       t = -900 /33.54 = -26.517

      |t| = |-26.517|=26.517

Degrees of freedom

                       γ = n-1 = 45-1 =44

t₍₀.₀₁ , ₄₄₎ = 2.326

The calculated  |t| = |-26.517|=26.517 > 2.326 at 0.01 level of significance

Null hypothesis is rejected at 0.01 level of significance

There is difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012

Choose the true statement.<br> 0-2 &lt;-3<br> 0-2&gt;-3<br> 0-2 = -3
Natasha2012 [34]

The true statement is -2>-3

Step-by-step explanation:

The given statement included inequality and comparison symbols. The numbers involved are negative integers.

As the number increases its value decreases which means that -1 will be greater than -2 and so on

Given statement will be discussed one by one

-2 <-3

-2 comes before -3 so the statement is true as -2 will be greater than -3.

-2>-3

The statement is true because -2 is greater than -3

The true statement is -2>-3
