6 A team of conservationists capture and measure the weight of 100 adult New Zealand kaka. The results are set out in the following table. Weight | Number of kakas (g) (frequency) 390-410 410-430 16 430-450 23 450-470 17 470-490 11 490-510 510-530 6. 530-550 6. 550-570 (a) Find the sample mean weight ī and standard deviation s. (b) Assuming that a and s are good approximations to u and o, fit a normal distribution to this data by obtaining the expected frequencies, to two decimal places. (c) Perform a goodness-of-fit test for the normal model and make a conclusion regarding the suitability of the model to describe this data.
