Hw stat | Mathematics homework help

download the attchment perfect and clear-up the forthcoming questions:

5.4.5(a, e), 5.4.6(a, d – use the consultation to response), 10.3.3, 10.3.7* deficiency Rsudio, 10.3.11*(use ds.10.3.13), 10.3.15, 10.4.3* deficiencys R, 10.4.9.

notice that the relieve attcahment perfect is the R methods for gist 10.3.7.

 

some aid after a while R:

5.4.5 - judgment crucial values from the chi-square dispensation: 
qchisq(probability, df, inferior.folinferior = F)
put the likelihood in primitive, then the degrees of insubservience. inferior.folinferior = F owing we constantly scantiness the exact folinferior after a while a chi-square dispensation.

5.4.6 - effect sconsideration you use the consultation to response these (see ordinance register)

10.3.7 - see laordeal canvas missive from me, I sent the method out. 

10.3.11 - I've been pointed some of you to do this by agency (which is quiescent my instruction) owing it achieve be amiable action for the ordeal. Use R to get the frequencies, then honest compute expected counts and chi-square statistic by agency. However, close is the method if some of you scantiness to do it that way. Either way achieve hold merit for doing the gist. 
probs = c(.04, .06, .80, .06, .04)
chisq.test(chem$Frequency, p = probs)

10.4.3 - This one is exploration for a ordeal for insurrection. the chisq.test() can do this ordeal, but the basis deficiencys to be in a fixed format, and its not abandoned to us in that format. Tclose are ways to fix this, but for this one, I would honest use R to get the two way freedom consultation, then compute expected counts and chi-square statistic by agency.
