Surveys, again, are of two types: 2. Cross-Sectional Surveys Cross-sectional surveys are used to collect data from a sample of the target population at a specific point in time. Researchers evaluate various variables simultaneously to understand the relationships and patterns within the data. Cross...
Simply put, type 1 errors are “false positives” – they happen when the tester validates a statistically significant difference even though there isn’t one. Source Type 1 errors have a probability of “α” correlated to the level of confidence that you set. A test with a 95%confidence ...

CExplanation: When you roll two fair six-sided dice, the sample space of the event will have 36 elements since both dice have six possible outcomes (6*6=36).The elements of the sample space where the numbers are equal are as follows:- (1,1) - this means that the first die results...
This is equivalent to asking for the probability that at least one of the numbers is a multiple of 5, since if one of the numbers is a multiple of 5, then the product with it and another integer is also a multiple of 5, and if a number is a multiple of 5, then since 5 is pri...
