Answer:
5%
Explanation:
a) What was the growth rate in sales between years 1 and 2
Growth rate measures the increase in the level of sales over a period of time
Growth rate from year 1 to 2 = (increase in sales from year 1 to 2 / sales in year 1) x 100
increase in sales from year 1 to 2 = 236.25 - 225 = 11.25
(11.25 / 225) x 100 = 5%
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.
