kes an average of 13.2 minutes for blood to begin clotting after an injury. An EMT wants to see if the rage will decline if the patient is immediately told the truth about the injury. The EMT randomly cted 55 injured patients to immediately tell the truth about the injury and noticed that they averaged minutes for their blood to begin clotting after their injury. Their standard deviation was 2.52 minutes. at can be concluded at the the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean p. The null and alternative hypotheses would be: Họ: p v = 13.2 H1: p v E. The test statistic t v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is s va f. Based on this, we should reject g. Thus, the final conclusion is that ... |the null hypothesis. O The data suggest that the population mean is not significantly less than 13.2 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is less than 13.2. O The data suggest the population mean is not significantly less than 13.2 at a = 0.10, so there is statistically significant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is equal to 13.2. O The data suggest the populaton mean is significantly less than 13.2 at a = 0.10, so there is statistically significant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is less than 13.2.

Sheila's doctor is worried that she might develop gestational diabetes during her pregnancy. There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if their glucose level is above 140 mg/dl one hour after consuming a sugary drink. Sheila's measured glucose level one hour after the sugary drink varies according to the Normal distribution, with p = 125 mg/dl ando = 10 mg/dl. Fill in the following blanks with the correct options: (a) If a single glucose measurement is made, the probability that Sheila is diagnosed as having gestational diabetes is (0.0668, 0.1587, 0.2525, or 0.3173?). (b) Assuming that the population mean is 125 mg/dl, imagine that we repeat taking all possible samples of size 4 from the population, then only about 1.3 out of (10, 100, or 1,000?) sample means will have values as large as (125 or 140?) cm or even larger.

please help me answer this all. if i divided it it just became hard explain it. please i give a thumbs up. answer this.
