Two different alloys are being considered for making lead-free solder used in the wave soldering process for printed circuit boards. a crucial characteristic of solder is its melting point, which is known to follow a normal distribution. a study was conducted using a random sample of 21 pieces of solder made from each of the two alloys. in each sample, the temperature at which each of the 21 pieces melted was determined. the mean and standard deviation of the sample for alloy 1 were = 218.9
