Using a 5% level of significance, test whether or not the proportion of people eating vegetarian meals at chicken bucket's canteen is different to that at New York University canteen. b. The total number of goals that Zambia scored when they were crowned African Champions were normally distributed with mean u and a standard deviation of 4. A sample of 25 goals is taken and the statistics G = X25 – X1 and D = X1 + X2 + X3 + .. + X25 .Find the distributions of the goals G and D c. The random variable x~N(µ, 0²) show that &~N(µ,)
