Answer:

The answer is NO. The experimental results did not support the claim that less than 0.2 percent of the company's batteries would fail during the advertised time period.

Explanation:

From the illustration, for 15 batteries to fail out of 5000 batteries that means a 0.3 percent failure. Hypothetically, since there has been a claim that about 0.2 per cent will fail and we now have a confirmed failure rate of 15 in 5000 or 0.3 per cent rate, then we can infer that the hypothesis of 0.2 percent may be incorrect after all since it is still less than the confirmed rate of 0.3 per cent failure. Thus, since 0.3 rate is higher than 0.2 rate, then the hypothesis is wrong by a margin  of 0.1 percent.

Novosadov [1.4K]

Answer:

A strictly dominant action produces: a higher payoff than any other action the player can use for every possible action of the other players.

Explanation:

A strictly dominant action does not play fair. Here, there is no equality because strict dominance requires all payoffs to be strictly greater.

A strictly dominant strategy is that strategy that always provides greater utility to a the player, no matter what the other player's strategy is.

A rational player will avoid a strictly dominated counterpart because if his opponent uses strictly dominated action he will be come out worse off regardless of which moves other players make.

Answer:

0.9717 per unit sold (approx)

Explanation:

Here, we are assuming 52 weeks in a year.

Contribution margin:

= (Sales revenue - variable cost) ÷ sales revenue

= [(3.52 × 10 + 3.52 × 0.18 × 540 × 52) - (3.52 × 0.26 × 551)] ÷ (3.52 × 10 + 3.52 × 0.18 × 540 × 52)

=  [(35.2 + 17,791) - (504)] ÷ (35.2 + 17,791)

= [17,826.2 - 504] ÷ 17,826.2

= 17,322.2 ÷ 17,826.2

= $0.9717 per unit sold (approx)
