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.

d1i1m1o1n [39]

Answer:

determine cash investing and financing transactions made during the period.

Explanation:

When you analyze the statement of cash flows, you can determine and predict how will operating cash flows be in the future. E.g. a project is generating high amounts of cash, so you can predict that it will continue to do so for some time. But what you cannot predict or even compare is related to the financial and investing transactions that the company will make in the future. E.g. by analyzing a cash flow you cannot know if the company will decide to invest in other projects or will it decide to issue more stocks.

mote1985 [20]
<span>The best explanation for Khalil's improved performance when he was taking the herbal medicine is the Placebo Effect. Sugar and basil leaves in the amount that a medicine dose contains would not have any significant effect on Khalil's performance, but the placebo effect can cause someone to see improvements from a placebo (a treatment with no active effect) simply because they expect to see improvements. Since Khalil expected improvements from taking the medicine, he might have perceived improvements from the placebo effect even though the medicine had no real effect.</span>

What is one explanation for why this labor supply curve is upward sloping over the range of wages from low wage to high wage?
hjlf

Answer:

Option 1 - the opportunity cost of leisure decreases as wages decrease.

Explanation:

The labour supply curve of any occupation will always be upward sloping because when wages, (the opportunity cost of leisure) rises, the more hours of leisure a staff will relinquish to do more work.  

The opposite of this is true as seen in option 1 of the question.

Opportunity costs will reduce with a consequent reduction in average wages. When fewer people want to retain their employment due to decrease in wage rates, it would lead to a fall in demand for leisure.
