The following data are the joint temperatures of the
O-rings $$^{\circ} \mathrm{F}$$ ) for each test firing or actual launch of the space
shuttle rocket motor

Construct a normal probability plot of the O-ring joint temperature data
Does it seem reasonable to assume that O-ring joint temperature
is normally distributed?

The following data are the viscosity measurements

for a chemical product observed hourly (read down, then left

to right).

$$\begin{array}{lllll}{47.9} & {48.6} & {48.0} & {48.1} & {43.0} & {43.2} \\ {47.9} & {48.8} & {47.5} & {48.0} & {42.9} & {43.6} \\ {48.6} & {48.1} & {48.6} & {48.3} & {43.6} & {43.2} \\ {48.0} & {48.3} & {48.0} & {43.2} & {43.3} & {43.5} \\ {48.4} & {47.2} & {47.9} & {43.0} & {43.0} & {43.0} \\ {48.1} & {48.9} & {48.3} & {43.5} & {42.8} \\ {48.0} & {48.6} & {48.5} & {43.1} & {43.1}\end{array}$$

(a) Draw a time series plot of the data

The following data are the joint temperatures of the

O-rings $$^{\circ} \mathrm{F}$$ ) for each test firing or actual launch of the space

shuttle rocket motor

$$84,49,61,40,83,67,45,66,70,69,80,58,68,60,67,72,$$

$$73,70,57,63,70,78,52,67,53,67,75,61,70,81,76,79,$$

$$75,76,58,31$$

Construct a normal probability plot of the O-ring joint temperature data

Does it seem reasonable to assume that O-ring joint temperature

is normally distributed?

yes $$\rightarrow$$ normal distribution
