Let x be a random variable that represents red blood cell count (RBC) in millions of cells per cubic millimeter of whole blood. Then x has a...

 1.  (H0: μ < 4.8; H1: μ = 4.8) 2.  (H0: μ > 4.8; H1: μ = 4.8) 3.  (H0: μ = 4.8; H1: μ ≠ 4.8) 4.  (H0: μ = 4.8; H1: μ > 4.8)

5.  (H0: μ = 4.8; H1: μ < 4.8)

(c)What is the value of the sample test statistic? (Round your answer to three decimal places.)    

(d)Find the P-value. (Round your answer to four decimal places.)    

(e) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level α? choose one

1. At the α = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant. 2. At the α = 0.01 level, we reject the null hypothesis and conclude the data are not statistically significant. 3. At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are statistically significant. 4. At the α = 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant (f) Interpret your conclusion in the context of the application.  choose one1. There is sufficient evidence at the 0.01 level to conclude that the population mean RBC count for the patient is lower than 4.80. 2. There is insufficient evidence at the 0.01 level to conclude that the population mean RBC count for the patient is lower than 4.80.
