Question

psychologist is measuring learning in mice. He assumes that a mouse learns to recognize a specific object after a random number of exposures, and the number is geometrically distributed with parameter p. He exposes one of his subject mice to 3 different objects on 3 different days and records the (independent) numbers of exposures: 4, 3, and 7.
A) Based on this data, what is the maximum likelihood estimate of p?
O 0.7857
O 0.2143
O 0.2727
O 0.1765

    Answer:

    Option B) 0.2143                                            

    Step-by-step explanation:

    We are given the following in the question:

    Numbers of exposures(x): 4,3,7

    We have to find the maximum likelihood estimate of p.

    Formula:

    \hat{p} = \dfrac{n}{\sum x_i}

    Putting the values, we get,

    \hat{p} = \dfrac{3}{3+4+7} = \dfrac{3}{14} = 0.2143

    Thus, the correct answer is

    Option B) 0.2143
