A company claims that its tablet computers have
an average recharge time of 3 hours. In a random
sample of these computers, the average recharge
time is 2.5 hours. You suspect that the average
recharge time might be less than what the
company claims. Let y represent the average
time, in hours, needed to recharge the company's
tablet computers.
What is the null hypothesis, H., for this situation?

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
