tamaranim1 [39]

Claim: the mean resting pulse rate for men is less than 72 bpm.

Symbolic form would be: μ < 72

Step 1: null hypothesis  : μ > =  7 2 b p m

Step 2: alternative hypothesis:  μ <  7 2 b p m



Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92


Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis


            P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.

Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.

Airida [17]

Answer:

B

Explanation:

Organic chemistry is defined as the study of carbon compounds.

Organic compounds were first thought to be compounds that could only be produced by living organisms. This theory was disproved when scientists synthetically made urea from ammonia in a lab.

Organic compounds are now known as compounds where carbon atoms are covalently bonded to other elements. This could be hydrogen or oxygen (in the case of lipids or carbohydrates) or nitrogen (in the case of amino acids).
