Musca domestica L. or common houseflies have wing lengths that are found to be normally distributed. To verify this, a Filipino biometrician measured the wing lengths (in cm) of 15 random houseflies in a certain area and the following data were obtained: 1.7 2.5 2.6 2.8 3.3 3.6 3.7 3.7 3.9 4.1 4.7 4.8 5.1 5.2 5.6 At 5% level of significance, test from the data if the mean wing length of common houseflies is not equal to 4.55 using the given R-software output: Note: write Ho and Ha both in symbols and in words.
