i need help with my homework. i need short explanation and correct answer. NEED ASAP.

It is known that the average resting-state aHFA (a measure of brain activity) for a cluster of neurons is 3.8mV. A group of researchers believes that rapid changes in motion activate this cluster: in other words, its aHFA should be different from the resting state value when a subject is tracking rapid changes in motion. The researchers take a random sample of 10 people, and perform an experiment: . Each person plays a round of ping-pong in a virtual reality game. . Each person's aHFA is recorded when their opponent hits the ball (rapid motion change). Since a round of ping pong can involve multiple back-and-forths, the researchers collect a total of 48 observations of aHFA. (i.e. multiple observations per person) The researchers conduct a hypothesis test at a = 0.05 by constructing a 95% confidence interval based on the established average value and the following statistics from their sample: Known resting-state aHFA: 3.8mV sample mean of 48 observations: x = 5.1mV sample size n = 48 sample standard deviation = 3.1mV Select the correct answer choice: What are the null and alternative hypotheses? O Ho : x =3.8mV vs Ha : x * 3.8mV O Ho : u = 3.8mV us Ha : u # 3.8mV O Ho : x = 3.8mV vs Ha : x > 3.8mV O Ho : u = 3.8mV vs Ha : M > 3.8mVIt is known that the average resting-state aHFA (a measure of brain activity) for a cluster of neurons is 3.8mV.

Known resting-state aHFA: 3.8mV . sample mean of 48 observations: 5; = 5.1mV - sample size n = 48 - sample standard deviation = 3.1mV Use the dropdowns to select the correct answer choices: Take on the role of the researchers and follow the steps below to conduct the hypothesis test at at oz 2 0,05 using a 95% confidence interval: 1. What is the point estimate for the Cl? 2. What is the standard error? [Select] V 3. What is the critical value required by our signicance level alpha = 0.05? [ Select] v 4. What is the margin of error? [ Select ] V 5. The CI thus constructed has a lower bound of [ Select ] V and an upper bound of [ Select ] 6. Since the 95% CI [ Select ] v Mo = 3.8, we [ Select ] the null hypothesis at significance level 0.05, and our conclusion is [ Select ] V
