Is a platelet count of 75 significantly low? We need to know if the patient "A" has cancer. Thrombocytopenia is a condition in which you have a low blood platelet count. Platelets (thrombocytes) are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries. A low platelet count is a blood disorder that has a long list of possible causes. The condition affects the ability of the blood to clot, and wounds can bleed severely with this condition. This can have severe complications in some cases. Explain your answer The lowest platelet count in a dataset is 75. Is that value significantly low? Assume that platelet counts have a mean of 239.4 and a standard deviation of s=64.2.

Platelet Counts Listed below are amples of platelet counts (number per $\mathrm{mm}^{3}$ ) from randomly sclected men and women (based on data from the National Health and Nutrition Examination Survey. Low platclet counts may result in excessive blecding, while high platder counts increase the risk of thrombosis. Use a 0.05 significance kvel to test the claim that men and women have platclet counts with the same standard deviation. $$\begin{array}{rllllllll} \text { Female: } & 224.0 & 364.5 & 468.0 & 323.5 & 306.5 & 264.5 & 233.0 & 254.5 & 463.0 \\ & 282.5 & 307.5 & 360.5 & 3155.0 & 284.0 & 259.5 & 252.5 & 369.0 & 471.0 \\ & 198.0 & 390.0 & 269.5 & 344.5 & 386.5 & 256.0 & 226.0 & 259.0 & 271.5 \end{array}$$ $$\begin{array}{llllllllll} \text { Male: } & 264.5 & 360.0 & 384.5 & 171.0 & 328.5 & 267.0 & 238.0 & 251.0 & 321.5 \\ & 282.5 & 291.5 & 164.0 & 199.5 & 220.0 & 245.0 & 266.0 & 369.0 & 210.5 \\ & 234.0 & 244.5 & 365.5 & 265.0 & 225.0 & & & & \end{array}$$

10. A patient's automated platelet count is 132 X 103/5L. Upon slide review, the patient's sample has rosettes of platelets surrounding the segmented neutrophils. A Na Citrate tube is collected on the patient. The CLS gets a 197 X 103/5L platelet count on the Na citrate tube. What is the correct platelet count to report to the physician? (3 pts.) 11. In the blank next to the term, write the number of the corresponding description (found below). (8 pts.) ____A. toxic granulation ____B.
