## data from Example 4.29

### Description

The `xmp04.29` data frame has 19 rows and 2 columns of dielectric breakdown voltages and their corresponding standard normal quantiles used in a normal probability plot.

### Format

This data frame contains the following columns:

Voltage
  a sorted numeric vector of the dielectric breakdown voltages measured on a piece of epoxy resin.
z.percentile
  a numeric vector of standard normal quantiles

    data(xmp04.29)
    attach(xmp04.29)
    ## compare to Figure 4.33, page 190
    qqp <- qqnorm(Voltage)
    qqline(Voltage)
    detach()
    ## compare quantiles with those given in book
    cbind(qqp, xmp04.29)
