Answer:

  • <u>You need to estimate: approximately 0.84</u>

Explanation:

Please, find attached a figure with the complete question, including the probability distribution.

<h2>Solution</h2>

The graph does not permit to read exact values, thus you must estimate.

  • P(X=6) ≈ 0.03
  • P(X=7) ≈ 0.13
  • P(X=8) ≈ 0.62
  • P(X=9) ≈ 0.14
  • P(X=10) ≈ 0.08

P(X ≥ 8) = P(X=8) + P(X=9) + P(X=10)

  • P(X≥8) ≈ 0.62 + 0.14 + 0.08 = 0.84

Dmitry [639]

From the ratio computed, the numbers will be 420 and 980.

<h3>How to calculate the ratio</h3>

From the information given, we are to divide 1400 in the ratio 7:3. The smaller number will be:

= 3/(3+7) × 1400

= 3/10 × 1400

= 420

The larger number will be:

= 7/10 × 1400

= 980

Therefore, the numbers will be 420 and 980.

You are testing a claim and incorrectly use the normal sampling distribution instead of the​ t-sampling distribution. Does this
Keith_Richards [23]

Answer:

From the given data, the typical appropriation is utilized rather than t distribution for testing. The thicknesses of the curve similarly influence both normal distribution and territory of t distribution. The normal distribution test and t test give a similar dismissal for the invalid theory for any tail of the test. Besides, the tests normal sampling distribution and t sampling distribution give a similar dismissal to null hypothesis.  

Along these lines, the outcomes got by utilizing normal distribution and t distribution are distinguished as same and for each situation, the tail thickness doesn't influence the event of the basic qualities.
