An IBM internship student designed two different user interfaces (e.g. UI1 and UI 2) for help age of 6-7 students to solve simple math problems. She would like to know which interface is better for improving their skills on solving math problems. The collected data include the attributes as UI1 test score, UI2 test score, Number of Electric devices they have at home, Age, Student Gender UI 1UI 2DevicesAgeGender51846 boy152037 girl152147 boy142257 boy121546 girl102036 girl142337 boy122546 girl162147 girl51956 boy61836 boy142657 girl152547 girl72856 boy92236 girl62947 boy152446 girl112036 girl62156 boy152347 girl152567 boy52246 boy72436 girl161557 girl152457 boy152367 boyFor this assignment, you need to apply t-test to find answers for the following research questions:Is there a significant difference between boys and girls UI1 test scores?Is there a significant difference between boys and girls UI2 test scores?Is there a significant difference between 6-year-olds and 7-year-olds UI1 scores?Is there a significant difference between 6-year-olds and 7-year-olds UI2 scores?Is there a significant difference between UI1 s scores with respect to the number of devices they have at home?Is there a significant difference between UI2 s scores with respect to the number of devices they have at home?Is there a significant difference between students UI1 and UI2 scores? 5 points per each question (you need to provide null & alternative hypothesis and both p- & t-value to get full credits).
