I believe Park University should retract its previous statement due to the confidence limit is between 61%-79%, not totally justified above the level.

H0: μ ≥ 3200 against H1: μ < -1.7823 when I rejected the null hypothesis.

These results are said to be noteworthy at a likelihood of p = 0.05. This implies just 5% of the time would you hope to see comparable information if the invalid theory were right; subsequently you are 95% certain that information does not fit a 3:1

7. Unfortunately, the χ2 test is mathematically unsuitable for use with averages. What statistical test could we use to determine if our average TRC is really the same as Holt’s (1952) data?

Example one, my landlord wants to know how satisfied his tenants are with their living conditions on a scale of 1 to 10. He can split the tenants into three age categories; 29 and under, 30-50, and 51 and over. The null hypothesis would be; all age groups are equally satisfied.

Now we need to check whether or not the calculated chi-square probability, p is less than or equal to α = 0.05 OR the Chi-Square value, χ2 from chi-square distribution tables is equal to or greater than α = 0.05. If p α OR χ2 α, we reject the null hypothes is and conclude that at the 0.05 significance level, there is a relationship between the row variables and column variables. Since p = 0.04285 < α = 0.05 (OR χ2 = 11.1 > α = 0.05) we conclude

If more beds are acquired, Mt. Sinai Hospital will have immediate additional cost of purchasing more beds as well as additional cost in the x-ray department as serving more patients will results in handling more x-rays. This optimal solution will use up its maximum unutilized capacity of 7,000 more x-rays.

a) The standard error of the mean, S.E. = /Sqrt(n) = 40,000/Sqrt(50) = 5656.8542

Does asymptotic mean that the normal curve gets closer and closer to the X-axis but never actually touches it?

Export and import price indices measure the rate of change of growth in international trade. However, dividing the two will lead to getting terms of trade. However, this report analyses the trends of export and import indices over the years from 2000 to 2015. The result depicts that overall change has been fluctuating but
