Explanation Given information: Let B be the Boolean algebra, with the operations, addition” + ”and multiplication” ⋅ ” Concept used: a ¯ + a = a + a ¯ by the commutative law = 1 by the complement law for 1 And a ¯ ⋅ a = a ⋅ a ¯ by the commutative law = 0 by the complement law for 0 Calculation: Let B be the Boolean algebra, with the operations, addition " + " and multiplication " ⋅ " . Suppose 1 and 1` are tile identity elements of B with respect to multiplication " ⋅ " . To show that there is only identity element of B with respect to multiplication " ⋅ " it is enough to show that 1 = 1 ` . The Identity law for multiplication " ⋅ " tells that, for all a ∈ B . a ⋅ 1 = a and a ⋅ 1 ` = a It follows that, a + 1 = a + 1 ` Add both sides with a ¯ , a ¯ + ( a ⋅ 1 ) = a ¯ + (

Definition of null hypothesis from the textbook Definition of alternative hypothesis from the textbook Imagine this: you suspect your beloved Chicken McNugget is shrinking. Inflation is hitting everything else, so why not the humble nugget too, right? But your sibling thinks you’re just being dramatic—maybe you’re just extra hungry today. Determined to prove them wrong, you take matters (and nuggets) into your own hands. You march into McDonald’s, get two 20-piece boxes, and head home like a scientist on a mission. Now, before you start weighing each nugget like they’re precious gold nuggets, let’s talk hypotheses. The average weight of nuggets as mentioned on the box is 16 g each. Develop your null and alternative hypotheses separately. Next, you weigh each nugget with the precision of a jeweler and find they average out to 15.5 grams. You also conduct a statistical analysis, and the p-value turns out to be 0.01. Based on this information, answer the following questions. (Remember,…
