A journal article reports that a sample of size was used as a basis for calculating a CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was . You decide that a confidence level of is more appropriate than the level used. What are the limits of the interval

The limit of the (228.533, 234.735)

Step-by-step explanation:

The values are missing in the given question. Therefore, in order to attempt this question, we will make assumptions.

So, let's assume that:

sample size of the journal article that was reported = 5

which is applied for determining a 95% CI

Also, assuming that the resulting interval = (229.764, 233.504)

However, if we are to use a 99% CI which we deemed to be more appropriate;

Then, our objective is to find the limits of this particular interval in question.

To do that:

We need to first find the sample mean at 95% CI by using the formula:

Since; df = n - 1

df = 5 - 1

df = 4

Then;

Sample mean = 231.634

Using the same formula to determine the standard deviation, we have:

At t = 0.025 and df = 4; = 2.776

s = 1.5063

The 99% CI is:

At t =0.005 and df =4; = 4.604

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
