The average mansanitas has approximately 200 seeds. A very patient CTU IE student selected a random sample of 10 mansanitas and found a sample mean of 185.2 seeds with a standard deviation of 10.

Question
B- Perform each of the following steps.
a. State the hypothesis and identify the claim
b. Find the critical value(s)
c. Find the test value
d. Make the decision
e. Summarize the results
1. The average mansanitas has approximately 200 seeds. A very patient CTU IE student selected a
random sample of 10 mansanitas and found a sample mean of 185.2 seeds with a standard
deviation of 10. At the 0.05 level of significance, can it be concluded that the mean is less than
200?
2. In 2020, 45.6% of Cebu motor vehicle accidents involved no improper driving. In an area
comprised of six adjoining cities, it was found that out of 110 randomly selected accidents, 60
involved improper driving in some way. At the 0.10 level of significance, is there sufficient
evidence to conclude that the proportion of accidents involving improper driving differs from the
2020 proportion?
3. Test the claim that the standard deviation of the number of aircraft stolen each year in the United
States (during the Trump administration) is less than 15 if a random sample of 12 years had a
standard deviation of 13.6, use alpha 0.05 value.
4. The average length of 'short hospital stays' for Covid-19 infected men is slightly longer than that
for women, 5.2 weeks versus 4.5 weeks. A random sample of recent hospital stays for both men
and women revealed the following. At alpha equals 0.01, is there sufficient evidence to conclude
that the average hospital stay for men is longer than the average hospital stay for women?
