Given: The data describes the lead concentration in μg/g measured in different traditional medicines. Random sample of data is: X = 4, 14.5, 21.5, 20.5, 2.5, 16.5, 21.5, 9, 11, 8.5 Sample size of data (n) = 10Solution: Claim = The mean lead concentration for all such medicine is less than 17 μg/g. The null and alternative hypothesis is: H0: μ=17H1: μ<17 Therefore, option D is correct. The required calculation for the test statistic shown below: Sample mean (X¯)=∑Xn=4+14.5+21.5+.......+8.510=12.95 Sample standard deviation (S)=1n-1∑X2-nX¯2=110-142+14.52+21.52+.......+8.52-10×12.952=7.0453 The test statistic can be calculated as: t=X¯-μSn=12.95-177.045310=-1.8178 Therefore, the test statistic is -1.82. The degrees of freedom is: df=n-1=10-1=9 At α=0.10 and df=9, the p-value for the test statistic of -1.8178 is: P(t>-1.8178)=0.0513 Therefore, the p-value is 0.051. The p-value is less than the significance level (α), so there is sufficient evidence to reject the null hypothesis. Therefore, Reject H0. There is sufficient evidence to conclude that the mean lead concentration for all such medicines is less than 17 μg/g.
