1- Assuming that your data set is the population of the daily returns is normally distributed, draw the normal distribution graph of the random variable X

To draw normal distribution graph of the random variable daily returns, descriptive statistics analysis was first calculated and the SPSS results are as shown below;

Descriptive Statistics
	N	Range	Minimum	Maximum	Mean	Std. Deviation	Variance
DlyReturn	1731	.114041	-.066634	.047407	.00045055	.009002043	.000
Valid N (listwise)	1731

2- What is the probability that if you randomly select any trading day its return is less than 0.2%? Draw the question on a normal curve and also screenshot the formula you use in SPSS to calculate the probability.

3-What is the probability that if you randomly select any 30 trading days that the sample mean daily return is less than 0.2%? Draw the question on a normal curve and also screenshot the formula you use in SPSS to calculate the probability.

4- If you randomly select 5 trading days, calculate the probability that the sample mean daily return will be negative? Draw the question on a normal curve and also screenshot the formula you use in SPSS to calculate the probability.
