Jupyter code in python

[jamoforeal]

Please can anyone help me identify the error in this code in my jupyter notebook
#Let's generate a random dataset that meets the above assumptions
import random

We will use random data for the samples and label them as 'a' and 'b' respectively

a = [random.gauss(50, 20) for x in range(30)] #a variable with a list of 50
b = [random.gauss(55, 15) for x in range(30)]

#If we assume the population mean is 40
#Null hypothesis is the sample mean = population mean(40)
#alpha=0.05
#Therefore, p<0.05 (reject null hypothesis)
#Let's test it for sample a
t_stat, p_value = stats.ttest_1samp(a, 40, axis=0)

#Print the t-stat and the p-value
print("T-statistic:", t_stat)
print("P-value:", p_value)
print(np.mean(a))

Did you import the numpy and scipy libraries?

and you need a

if p_value < 0.05:
print("reject null hypothesis")
else:
print("not reject null hypothesis")

and your a and b is creating a list of 30 with values ​​from 20 to 50 and not a list of 50 as you say in the code comments
