A.
For 12 - 1,
82 - 78 = 4 degrees per hour
For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour
For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour
For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour
The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change
Answer/Step-by-step explanation:
(a) The likelihood function to estimate this probability can be written as:
mat[1000, 9800]p9580(1 - p)420
(b) The value of the maximum likelihood estimate of the probability 0.958(By taking log of expression in (a) above)
(c) when the true probability is 98%, then it implies that 9800 of 10,000 bulbs did last over 6500hours.
Therefore, the likelihood is p(9800) = mat[10000, 9800]p9800(1 - p)200
(d) Method of moments estimate is the estimation of all the parameters of the population sample.
(e) The statement is FALSE because estimates by the method of moments are not necessarily sufficient statistics, because sometimes fail to take into account all relevant information in the sample. As in the above question
