An experiment is conducted to compare the maximum load capacity in tons​ (the maximum weight that can be tolerated without​ brea

king) for two alloys A and B. It is known that the two standard deviations in load capacity are equal at 7 tons each. The experiment is conducted on 30 specimens of each alloy​ (A and​ B) and the results are x overbarAequals65.6​, x overbarBequals60.6​, and x overbarAminusx overbarBequals5. The manufacturers of alloy A are convinced that this evidence shows conclusively that muAgreater thanmuB and strongly supports the claim that their alloy is superior. Manufacturers of alloy B claim that the experiment could easily have given x overbarAminusx overbarBequals5 even if the two population means are equal. Complete parts​ (a) and​ (b) below.

fiasKO [112]

Answer:

She deposits $350 into the account at the beginning of the year.

Step-by-step explanation:

Let us assume that Keegan deposits $P into her savings account at the beginning of the year.

The account earns 3% simple interest each year and she has $360.50 in her account at the end of the year.

If Keegan did not make any additional deposits or withdrawals during the year.

So, we can write that P[1+\frac{3}{100} ]= 360.50

⇒ P = $350 (Answer)

A coin is to be spun 25 times. Let x be the number of spins that result in heads (H). Consider the following rule for deciding w
larisa [96]

Answer:

0.0433

Step-by-step explanation:

Since we have a fixed number of trials (N = 25) and the probability of getting heads is always p = 0.05, we are going to treat this as a binomial distribution.

Using a binomial probability calculator, we find that the probability of obtaining heads from 8 to 17 times is 0.9567 given that the con is fair. The probability of obtaining any other value given that the coin is fair is going to be:

1 - 0.9567 = 0.0433

Since we are going to conclude that the coin is baised if either x<8 or x>17, the probability of judging the coin to be baised when it is actually fair is 4.33%
