vovangra [49]

Answer:

Accept the claim that mean = 8.2oz.

Step-by-step explanation:

Given that a company claims that its coffee cans contain 8.2 ounces of coffee, on average.

To check this, normally large samples are drawn and sample mean is calculated

Then hypotheses created as

H0: Mean = 8.2

Ha: Mean not equals 8.2

The std deviation of sample is found out and then 95% confidence interval is calculated.

If the sample mean falls within 95% confidence interval, then we are 95% confident that for large samples, the sample mean would fall within this interval. Also the claim can be accepted.

Hence conclusion is accept null hypothesis that mean = 8.2 oz.

A sample was taken of the salaries of 20 employees from a large company. The following are the salaries (in thousands of dollars
seropon [69]

Answer:

21,500

Step-by-step explanation:

Given data ( in thousand ) in this year,

28 31 34 35 37 41 42 42 42 47 49 51 52 52 60 61 67 72 75 77,

If each data is increased by $ 3000 in the next year,

So, the data for the next year,

31 34 37 38 40 44 45 45 45 50 52 54 55 55 63 64 70 75 78 80,

Since, the data is already arranged in the ascending order,

The median is 51 which is between 50 and 52,

Thus, the lower half of the Data is, 31 34 37 38 40 44 45 45 45 50,

Having median Q_1=\frac{40+44}{2} = \frac{84}{2} = 42,

Upper half of the data is 52 54 55 55 63 64 70 75 78 80,

Having median Q_3=\frac{63+64}{2}=\frac{127}{2} = 63.5

Hence, the interquartile range = Q_3-Q_1

= 63.5 - 42

= 21.5

That is, the Interquartile range would be 21, 500.

Prove the theorem which states that the angle subtended by a cord is twice at the centre than at the circumference
Novay_Z [31]

9514 1404 393

Explanation:

<u>Given</u>:

  • The attached figure showing circle O, chord BC, central angle BOC and inscribed angle BAC
  • angle BAC = α + β

<u>Prove</u>:

  • angle BOC = 2×angle BAC

<u>Proof</u>:

∠BOA +∠BOC +∠AOC = 360° . . . . . sum of arcs of a circle is 360°

2α +∠BOA = 180°, 2β +∠AOC = 180° . . . . . sum of triangle angles is 180°

∠BOA = 180° -2α, ∠AOC = 180° -2β . . . . solve statement 2 for central angles

(180° -2α) +∠BOC +(180° -2β) = 360° . . . . . substitute into statement 1

∠BOC = 2(α +β) . . . . . add 2α+2β-360° to both sides

∠BOC = 2×∠BAC . . . . . substitute given for α+β; the desired conclusion
