A company claims that its packages of beads contain, on average, 50 beads with a standard deviation of 5. 4 beads. In a hypothesis test of this claim, H0 is µ = 50 and Ha is µ ≠50, where µ is the average number of beads per package. Based on a sample of 20 packages, Celia calculates a mean of 52. 5 beads per package. Formula for z-statistic: z = StartFraction x overbar minus mu Over (StartFraction sigma Over StartRoot n EndRoot EndFraction) EndFraction What is the z-statistic for the sample? Round the answer to the nearest hundredth. Z =.
