Need step by step explanation, answers and six step hypothesis test

1.A biologist was interested in determining whether sunflower seedlings treated with an extract from Vinca minor roots resulted in a lower mean height of sunflower seedlings with the same standard deviation than the standard height of 15.7 cm with a standard deviation of 2.35 cm. The biologist treated a random sample of 33 seedlings with the extract and subsequently obtained a mean of 13.66 cm and a standard deviation of 2.54 cm.

a.Show all 6 steps of a hypothesis test to determine if the mean height of seedlings treated with the extract is less than the standard height.Use = 0.05.

b.Show all 6 steps of a hypothesis test to determine if the standard deviation of the heights of seedlings treated with the extract differs from the standard deviation of standard heights.Again, use = 0.05.
