Answer:
14.3kg
Explanation:
Given parameters:
Quantity of heat = 149000J
Change in temperature = 5.23°C
specific heat of the ice = 2000J/kg°C
Unknown:
Mass of the ice in the bag = ?
Solution:
The heat capacity of a substance is given as:
H = m c Ф
H is the heat capacity
m is the mass
c is the specific heat
Ф is the temperature change;
since m is the unknown, we make it the subject of the expression;
m = H/ mФ
m = 
= 14.3kg

Since Arthur has developed a hypothesis and now is designing a study to test it, the answer which can provide the best guidance regarding his choice of measures, types of data to be collected, and methods for interpreting the data is the scientific literature in his area of interest.
Books and other research can help Arthur a lot when it comes to testing his hypothesis, because perhaps there have been other similar experiments that may aid him in putting his to the test.
