Suppose a friend tells you that the average length of trout caught in Pyramid Lake is u = 19 inches. However, a survey reported that of a random sample of 46 fish caught, the mean length these data indicate that the average length of a trout caught in Pyramid Lake is less than u = 19 inches? Use a = 0.05. LA USE SALT (a) What is the level of significance? 0.05 State the null and alternate hypotheses.

Explain the rationale for your choice of sampling distribution. The Student's t, since we assume that x has a normal distribution with known o. The standard normal, since we assume that x has a normal distribution with unknown o. The Student's t, since n is large with unknown o. The standard normal, since we assume that x has a normal distribution with known o. Compute the z value of the sample test statistic. (Round your answer to two decimal places.) (c) Find (or estimate) the P-value. (Round your answer to four decimal places.)

[0.74/1 Points] DETAILS PREVIOUS ANSWERS BBBASICSTAT MY NOTES A Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about a = 28 ml/kg.+ Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell 30 27 40 37 30 36 29 Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and o = 4.75. Do the data indicate that Roger's red blood cell volume is different (either way) from u = 28 ml/kg? Use a 0.01 level of significance. (a) What is the level of significance? 0.01 State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? O Ho: u = 28 ml/kg; H : u # 28 ml/kg; two-tailed O Ho: u # 28 ml/kg; H: u = 28 ml/kg; two-tailed O Ho: 4 = 28 ml/kg; Hj: 4 28 ml/kg; right-tailed (b) What sampling distribution will you use?
