what is the Z for 99% CI????

What happens to the width of the interval if the confidence level goes from 95% to 99%?

No, as it does not contain the conference Interval.

What would happen to the width of the interval if the sample size was n=9?

As the margin of error decreases when sample size increases. Hence, the confidence interval becomes wider.

What would happen to the width of the interval if the sample size was n=100?

If n = 100 then, the 95% confidence interval is given by; = xbar - + tc*(sigma/sqrt(n))

= 12.6 -+ 1.96*(1.96/sqrt(100)) C.I (12.09,13.10). As the margin of error decreases when sample size increases. Hence, the confidence interval becomes narrower.

Please answer in more detail?

Would a sample mean of 14.2 fall within the 95% CI for RR?  

For a certain harmonic oscillator of mass 2.88×10−25 kg, the difference in adjacent energy levels is 4.82×10−21 J. Calculate the force constant (in N/m) of the oscillator.

A circular glass plate has a diameter of 350 mm (13.78 in) and athickness of 10 mm (0.394 in). The edge of the plate is clamped,and air at 258C (778F) is on both sides of the plate. Determine the transmission loss for the plate for a frequency of [A] 250 Hz and [B]1000 Hz.
