Hi while i'm executing below getting error like
Indentation error : unindent does not match any outer Indentation level
Ingency if np.any (observed < 0)
TypeError : '<' not supported between instances of 'Prettytable' and 'init'

from prettytable import PrettyTable
t = PrettyTable(['Marital Status','Middle school', 'High School','Bachelor','Masters','PhD'])
t.add_row(['Single',18,36,21,9,6])
t.add_row(['Married',12,36,45,36,21])
t.add_row(['Divorced',6,9,9,3,3])
t.add_row(['Widowed',3,9,9,6,3])
print (t)
from scipy.stats import chi2_contingency
from scipy.stats import chi2
stat,p,dof,expected = chi2_contingency(table)
prob = 0.95
critical = chi2.ppf(prob, dof)
if abs(stat) >= critical:
print('Dependent (reject H0)')
else:
print('Independent (fail to reject H0)')

Answer 1

Which line does the error ref?

Answer 2

File "app.py", line 11, in <module>

Answer 3

line 10: you named the pretty table t and not table, did you?

Answer 4

Yeah even if I'm giving t also it's giving me error
