The 95% confidence interval will be wider than the 90% confidence interval.

In statistics, the likelihood that a population parameter will fall between a set of values for a certain percentage of the time is referred to as a confidence interval. Analysts frequently employ confidence ranges that include 95% or 99% of anticipated observations. Therefore, it may be concluded that there is a 95% likelihood that the real value falls within that range if a point estimate of 10.00 with a 95% confidence interval of 9.50 - 10.50 is derived using a statistical model.

  • The level of certainty or uncertainty in a sampling process is measured by confidence intervals.
  • Additionally, they are employed in regression analysis and hypothesis testing.
  • To determine statistical significance, statisticians frequently combine confidence intervals with p-values.
  • 95% or 99% confidence levels are most frequently used in their construction.

An income statement for Sam's Bookstore for the first quarter of the year is presented below: Sam's Bookstore Income Statement F
yawa3891 [41]

Answer:

The contribution margin for Sam's Bookstore for the first quarter is 0.84 or 84 %

Explanation:

Contribution Margin = Contribution ÷ Sales

Where,

<em>Contribution = Sales - Variable Costs</em>

where,

Sales :

Sales = $ 900,000

Number of Books Sold = $ 900,000 ÷ $50

                                      = 18,000 books

Variable Costs Calculation :

Cost of goods sold                                                           $630,000

Variable selling expenses ($5 × 18,000 books)               $90,000

Variable administrative expenses( 4% × $ 900,000)       $36,000

Total Variable Costs                                                         $756,000

Therefore,

Contribution Margin =  $756,000÷  $ 900,000

                                  = 0.84 or 84 %
