2022-05-09

Identify each of the following statements as true or false in relation to confidence intervals (CIs). 
Note: 0.5 marks will be taken away for each incorrect answer. The minimum score is 0.

 

 TrueFalse
A 95% CI is a numerical interval within which we are 95% confident that the true mean μμ lies.  
A 95% CI is a numerical interval within which we are 95% confident that the sample mean x¯¯¯x¯ lies.  
The true mean μμ is always inside the corresponding confidence interval.  
For a sample size n=29n=29, the number of degrees of freedom is n=30n=30.  
If we repeat an experiment 100 times (with 100 different samples) and construct a 95% CI each time, then approximately 5 of those 100 CIs would notnot contain the true mean 𝜇.

A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm. 
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

Confidence interval for parameter
X1,X2,,Xn- i.i.d observations
X1=ξ+η where ξ~N(θ2,θ2+1),η={0,1/24θ,1/2,ξ and η and η are independent.
Find α-confidence interval.
The first that I need to do is to find some estimate for θ. The only one that I find is 5XS2+110 but it is difficult to find distribution.
Is it possible to do something else?
