HYPOTHESIS STATEMENT
“The percentage of people suffering from a right bundle block in the heart is more than 8% for a
general population of 25 people with a confidence of 95%.”

NULL AND ALTERNATE HYPOTHESIS STATEMENTS:
Null hypothesis:“Prevalence of right bundle blockage in a general
population of 25 people is equal to 8%”.
Alternate hypothesis:“Prevalence of right bundle branch block in a
general population of 25 people is less than 8%.”

SIGNIFICANCE LEVEL INTITALIZATION:
We are 95% confident in our hypothesis. Hence we are initializing a significance level of 0.05.

Critical value (at alpha= 0.05) =0.39844
alpha
CVT value obtained = 0.1814

TESTING:The critical value is found by looking at the value
of P(z) at the significance value .i.e. 0.05.The critical value was found to be 0.39844.Mean of data was found to be = 2.66 people in
every 25 people.Standard deviation of data is 2.166 in every 25
people.Test value was found to be 0.01814.

RESULT:
The test value was found to be lesser than the critical value.
Hence we arrive at the conclusion that the hypothesis taken was wrong as the presence of alternate hypothesis was established.
