Solution: We are given a population follows a normal distribution with Mean and standard deviation
According to central limit theorem, if we have a population with mean and standard deviation and take large samples from the population, then the distribution of samples means will be approximately normally distributed with mean and standard deviation given below:
Therefore, for the given example the distribution of sample means will be approximately normal with mean and standard deviation given below:
rounded to 2 decimal places.
To solve the problem we will use the basic exponent properties.

Answer:
Assessing the association between supplemental vitamin A exposure and mortality and morbidity for measles:
Regarding the relative risk, the correct statement is:
a. Exposure to vitamin A appears to protect against morbidity and mortality for measles.
Step-by-step explanation:
Relative risk for incidence of measles = 0.75
Relative risk for measles mortality = 0.5
Relative risk for mortality and morbidity for measles = 0.375 (0.75 * 0.5)
The combined relative risk is less than 50%
The association is weak because RR is less than 1.
Therefore, there is no association between supplemental vitamin A exposure and mortality and morbidity for measles.
Experimental data are collected as: x[100]={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 2

Answer:
y = 1.754 + 1.001 x
Step-by-step explanation:
The equation of Regression equation is of the form of:
y = a + bx
where, a is intercept and b is slope
The formula for a and b is given by,
Thus, a = 1.754
and b = 1.001
Thus, Regression Line is given by,
y = 1.754 + 1.001 x
Now plotting these line:
