Let x be a random varlable that represents red blood cell count (RBC) In millions of cells per cublc millimeter of whole blood. Then x has a distribution that is approximately normal. For the population of healthy female adults, suppose the mean of the x distribution is about 4.64, Suppose thut
a female patient has taken stx laboratory blood tests over the past several months and that the RBC count data sent to the patlent's doctor are as follows.
4.9 4.2 4.5 4.1 4.4 4.3
() Use a calculator with sample mean and standard devlation keys to find x and s. (Round your answers to two decimal places.)
(u) Do the given data Indicate that the population mean RBC count for this patient is lower than 4.64? Use a = 0.05.
(a) what is the level of significance?
State the null and alternate hypotheses.
O Ho: H < 4.64; H:H= 4.64
O Ho: H = 4.64; H: H-4.64
O Hg: H = 4.64; H: H< 4.64
O Hạ: 4 > 4.64; H:- 4.64
O Ho: H-4.64; H:u> 4.64
(b) What sampling distribution will you use? Explain the rationale for your cholce of sampling distribution.
O The Student's t, since we assume that x has a normal distribution and o is known.
O The standard normal, since we assume that x has a normal distribution and o Is unknown.
O The standard normal, since we assume that x has a normal distribution and o is known.
O The Student's t, since we assume that x has a normal distribution and o is unknown.
What is the value of the sample test statistic? (Round your answer to three decimal places.)
(c) Estimate the P-value.
O P-value> 0.250
O 0.125 < p.value < 0.250
O 0.050 < p-value <0.125
O 0.025 < p-value 0.0so
O 0.005 < P-value <0.025
O P-value < 0.005
Sketch the sampling distribution and show the area coresponding to the P-value.
