laboratory claims that the mean sodium level, , of a healthy adult is 2 mɛq per liter of blood. To test this claim, a random sample of 20 adult atients is evaluated. The mean sodium level for the sample is 133 mEg pe ter of blood. It is known that the population standard deviation of adul odium levels is 14 mEq. Assume that the population is normally istributed. Can we conclude, at the 0.01 level of significance, that the opulation mean adult sodium level differs from that claimed by the aboratory? erform a two-tailed test. Then complete the parts below. arry your intermediate computations to three or more decimal places, nd round your responses as specified below. (If necessary, consult a
