Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p= 0.5 versus H1: p> 0.5 n= 125; x= 78, a = 0.1 Is npo (1- Po) 2 10? Yes No Use technology to find the P-value. P-value = (Round to three decimal places as needed.)

Find the p-Value The claim is that for a smartphone carrier's data speeds at airports, the mean is p=14.00 Mbps. The sample size is n=29 and the test statistic is t=1.035. The claim is that for 12 AM body temperatures, the mean is p>98.6°F. The sample size is n=3 and the test statistic is t=2.233. P-value = (Round to three decimal places as needed.)

esc DATAfile: Business Travel (a) 66°F Mostly sunny ? Current Year You may need to use the appropriate technology to answer this question. The Global Business Travel Association reported the domestic airfare (in dollars) for business travel for the current year and the previous year. Below is a sample of 12 flights with their domestic airfares shown for both years. 345 526 420 216 285 405 635 710 605 517 570 610 2 Ho: H0 Ha: μ = 0 Hod=0 HO Previous Year 315 463 462 206 275 432 585 650 545 547 Formulate the hypotheses and test for a significant increase in the mean domestic airfare for business travel for the one-year period.

A test is made of: Ho u=6 versus H₁: 6 Part: 0/3 Part 1 of 3 (a) The test statistic is z=0.63. Find and interpret the P-value. Round your answer to at least 4 decimal places. The P-value is P= X

Cardiology, Radiology The conventions of cardiac echocardiography are derived from comprehensive studies performed by technicians and cardiologists. Traditionally, patients are positioned supine (i.e., lying on their back), although there is no evidence to support this practice. Clinicians in the emergency department (ED) are sometimes faced with acutely ill patients who cannot tolerate the supine position. For this reason, a study is planned to compare ultrasound studies performed while a patient is supine vs. while a patient is upright. Patients 18 years of age who present to the ED with chest pain or shortness of breath and consent to the study will be enrolled. Each patient will receive two ultrasound studies, one in the supine position and one in the upright position. The order of administration of the two studies will be at random. Readers will review the images in a blinded manner and assess a number of clinical characteristics. An important endpoint is pericardial effusion (or…

MORE BENEFITS OF EATING ORGANIC Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data. In this case, we are testing Họ : Po = Pc Ha: Po > Pc where p, and p. represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. Use a 5 % significance level. Effect of Organic Bananas After 25 Days After 25 days, the proportion of fruit flies eating organic bananas still alive is 0.45 , while the proportion still alive eating conventional bananas is 0.42. The standard error for the difference in proportions is 0.029. What is the value of the test statistic? Round your answer to two decimal places. z = i What is the p-value? Round your answer to three decimal places. p-value = What…

Urgently need this solved please

Test the hypothesis using the​ P-value approach. Be sure to verify the requirements of the test.  H0​: p=0.6 versus H1​: p>0.6 n=250; x=1605, a=0.01 Is np 0 ( 1−p0) ≥​10? Use technology to find the​ P-value.​P-value?

Determine whether the outcome is a Type I error, a Type II error, or a correct decision. A test is made of H0: μ = 28 versus H1: μ ≠ 28. The true value of μ is 29 and H0 is rejected.
