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 1. Using visual inspection with the given histogram and Q-Q Plot below, do the data show evidence that the wing length of common houseflies follows the normal distribution? Explain by interpreting each graph. Figure 1. Histogram Figure 2. Q-Q Plot 2. Using the Wilk-Shapiro Test with R software output given below, do the data show evidence that the wing length of common houseflies follows the normal distribution at a=1%? Complete the following steps: Shapiro-Wilk normality st wing_length W = 0.97258, p-value = 0.8942 data: Но: На: Decision Rule: p-value: Decision: Conclusion: 3. Find a point estimate of the true mean wing length of common houseflies.
