Use a t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively normal. Assume that differences are computed using d=x₁-x₂. Test Ho: a = 0 VS Ha : µd ‡ 0 sample results x, = 16.97, sa = 14.0, na = 25. Part 1 Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p- value to three decimal places. test statistic = using the paired difference p-value= Part 2 Give the conclusion using a 5 % significance level. Reject Ho. Do not reject Ho.
An experiment consists of recording the patient's gender; Male (M) or Female (F), then his/her Blood Pressure Level; Normal (N), Elevated (E) or High (H). The sample space of the experiment will be: O S-(NM, EM, HM, NF, EF, HF} O S=(MN, ME, MH, FN, FE, FH) O =-{MF, NEH} O S=(M, F, N, E, H}

Determine the minimum sample size required when you want to be 99% confident that the sample mean is within one unit of the population mean and σ=12.3. Assume the population is normally distributed.
The random variable x has a normal distribution with mean 50 and variance 9. Find the value of x, call it x0, such that: a) P(x ≤ xo) = 0.8413 b) P(x > xo) = 0.025 c) P(x > xo) = 0.95 d) P(41 ≤ x ≤ xo) = 0.8630
X ~ N(60, 14). Suppose that you form random samples of 25 from this distribution. Let X be the random variable of averages. Let ΣX be the random variable of sums.Give the distribution of X. Sketch the graph, shade the region, label and scale the horizontal axis for X, and find the probability. (Round your answer to four decimal places.) P(X < 60) =.Find the 30th percentile.
