1A hypothesis test gives [blank_start]significant[blank_end] evidence to claim that an [blank_start]unknown[blank_end] [blank_start]parameter[blank_end] (such as mean or median) actually takes a [blank_start]specific[blank_end] [blank_start]value[blank_end] based on the [blank_start]sample[blank_end] [blank_start]statistics[blank_end]

2Type I error is when you [blank_start]reject[blank_end] the [blank_start]null[blank_end] hypothesis but it is actually [blank_start]true[blank_end], otherwise known as a false [blank_start]positive[blank_end]. Type II error is when you [blank_start]accept[blank_end] the [blank_start]null[blank_end] hypothesis but it is actually [blank_start]false[blank_end], otherwise known as a false [blank_start]negative[blank_end].
