Does a bigger confidence level have a smaller or bigger confidence interval?

Serga [27]3 years ago

Answer: Smaller!  I GOT YOU! I think you mean "there is a smaller chance of obtaining an observation outside that interval". Unfortunately, a Confidence Interval may not mean what it appears to mean, due to technical, statistical issues, but in general the narrower the interval (at a given confidence level) the less uncertainty there is about the results. There are many threads on this site discussing what a Confidence Interval means (as opposed to, say, a Credible Interval). We're not even getting into Predictive Intervals

Step-by-step explanation: i hope this helps let me know if it dues! :)

A cashier is unsure whether a group of customers ordered and ate a large or a medium pizza. Medium pizzas have a diameter of 12
Vinvika [58]
Answer: large pizza

Work:


1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.

2) First, calculate the total circumference of each pizza.

Formula for the circumference: 2π×radius

radius = diameter / 2

medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in

large pizza: 2π (16/2) = 16π ≈ 50.27 in

3) arc of a 1/12 sector

arc of a 1/12 sector = circumferece × 1/12

medium pizza: 37.70 in / 12 = 3.14 in


large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25


So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.
