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:
The amplitude of the subsequent oscillations is 13.3 cm
Explanation:
Given;
mass of the block, m = 1.25 kg
spring constant, k = 17 N/m
speed of the block, v = 49 cm/s = 0.49 m/s
To determine the amplitude of the oscillation.
Apply the principle of conservation of energy;
maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced
Therefore, the amplitude of the subsequent oscillations is 13.3 cm
