7. [-/4 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Head movement evaluations are important because disabled individuals may be able to operate communications aids using head motion. A paper reported the accompanying data on neck rotation (in degrees) for 14 subjects both in the clockwise direction (CL) and in the counterclockwise direction (CO). For purposes of this exercise, you can assume that the 14 subjects are representative of the population of adult Americans. Subject 1 2 3 4 5 6 7 8 9 10 11 12 13 14 CL: 57.6 35.7 54.5 56.8 51.1 70.8 77.3 51.6 54.7 63.6 59.2 59.2 55.8 38.9 CO: 44.4 52.1 60.2 52.7 47.2 65.6 71.4 48.8 53.1 66.3 59.8 47.5 64.5 34.8 Based on these data, is it reasonable to conclude that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction? Carry out a hypothesis test using a significance level of 0.01. (Use $\mu_{CL} - \mu_{CO}$.) Find the test statistic. (Round your answer to two decimal places.) t = Find the df. df = Use technology to find the $P$-value. (Round your answer to four decimal places.) P-value = State your conclusion. $\circ$ Reject $H_0$. We do not have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. $\circ$ Reject $H_0$. We have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. $\circ$ Fail to reject $H_0$. We do not have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. $\circ$ Fail to reject $H_0$. We have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction.

1. Explain/Discuss and give the reasons, as presented in the case history, the most likely fungal agent associated with this patient. 2. Illustrate, label, and describe the microscopic findings of the culture of the suspect organism at 37°C and 25°C. 3. Is this organism considered to be dimorphic? Explain, in detail, the reasons for your response. 4. Identify the antifungal agents which may possibly be used to treat the fungal infection. CASE: Large amounts of purulent discharge and drusen from the lower duct. In the diagnostic scheme used to identify Gram-positive, branched, and radially arranged bacilli-like organisms, were found in the direct preparation made from the samples from the lacrimal ducts.
