Question regarding error "x and y lengths differ"
...an for each one of our samples. Now let¢s compute and plot the
confidence intervals for the 50 samples:> m = 50; n = 40; mu = mean(pop);
sigma = sd(pop);
> SE = sigma/sqrt(n) # Standard error in mean
> alpha = 0.10 ; zstar = qnorm(1-alpha/2); # Find z for 90%
confidence
> matplot(rbind( samp_mean - zstar*SE, samp_mean +
zstar*SE),rbind(1:m,1:m), type="l", lty=1);
> abline(v=mu)
I am receiving the error "Error in xy.coords(x, y, xlabel, ylabel, log =
log) :
'x' and 'y' lengths differ" when inputting >matplot(rbind( samp_mean -
zstar*SE, samp_mean...
