I've been playing Minecraft with my son, and I was really into digging for ore. Curious, I wanted to see if the frequency of ore he claimed I would obtain was accurate (a = 0.10). The probabilities and observed quantities are listed below for ore mined (only those listed below were included in the sample): Ore Iron Lapis Lazuli Gold Redstone Diamond Emerald Observed 1,051 118 187 189 38 19 Expected 60% 8% 15% 13% 3% 1% What is the test statistic value for this hypothesis test? Round your answer to 4 decimal places.
