Question

Medical practitioners are increasingly utilising the Zoom platform. Not only for online meetings but also for consultations with patients. The weekly Zoom access time (in hours) at two hospitals:

Health Care I
Health Care II

needs to be investigated.

Given: The weekly access time of medical practitioners at both hospitals is normally distributed with a standard deviation of σ=5σ=5 hours.

Your assistance is greatly apprecited, Thank you.

Research Question 2: Does the mean weekly access time differ from 30 hours?
Given: The 90% confidence interval for
is:
(25.5 , 28.6)
Complete the following:
According to the observed confidence interval, the null hypothesis is
and there is sufficient evidence to claim that the average
access time
from 30 hours, at 0.1 level of significance.
According to the observed confidence interval, we know that:
True False
For every 100 random samples drawn, we expect that 90 of the confidence intervals will
contain the sample mean.
We are 90% confident that u is between 25.5 and 28.6.
The probability that u is between 25.5 and 28.6 is 0.9.
90% of all samples should have sample means between 25.5 and 28.6.
90% of all medical practitioners at Health Care II have access times between 25.5 and 28.6
hours.
For every 100 random samples drawn, we expect that 90 of the confidence intervals will
contain the population mean.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
