3 Section 7.1 K Part 1 of 4 Points: 0 of 1 Save State Ho and H in words and in symbols. Then determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning. Sketch a normal sampling distribution and shade the area for the P-value. A manufacturer of grandfather clocks claims that the mean time its clocks lose is more than 0.03 second per day. State the null hypothesis in words and in symbols. Choose the correct answer. A. The null hypothesis expressed in words is, "the mean time its clocks lose is no less than 0.03 second per day." The null hypothesis is expressed symbolically as, "Ho: ≥0.03." B. The null hypothesis expressed in words is, "the mean time its clocks lose is no more than 0.03 second per day." The null hypothesis is expressed symbolically as, "Ho: μ≤0.03." C. The null hypothesis expressed in words is, "the mean time its clocks lose is not 0.03 second per day." The null hypothesis is expressed symbolically as, "Ho: μ0.03." D. The null hypothesis expressed in words is, "the mean time its clocks lose is 0.03 second per day." The null hypothesis is expressed symbolically as, "Ho: μ=0.03."
