Answer:
See explaination
Explanation:
a) The alternate hypothesis for the study is:
H1: There is a significant difference between mean grade of male and female students.
b) The null hypothesis is:
H0: There is no significant difference between mean grade of male and female students.
c) The Level of Significance is 0.05
d) The computed t critical value for the study is 0.632
e) The P-value of the test is 0.531
f) Conclusion: The p-value of t test is greater than 0.05. Hence we accept null hypothesis at 5% level of significance and conclude that there is no significant difference between mean grade of male and female students

Answer:

Explanation:
As we know that the speed of sound in air is given as

now the rate of strike is 1 stroke per second
so distance is given as

now we will have


so the distance is given as
