Tories bookcase holds one algebra book one geometry book and 12 books about advanced engineering mathematics. Books are taken at random from her book case, one after another without replacement until an engineer book is had, at which no more books are taken. The random variable Z represents the total number of books taken during this experiment.

Natasha contributes land to the newly formed Romanoff Partnership in exchange for a 40% interest. The land's adjusted basis and fair market value is $540,000. It is subject to a $300,000 liability, assumed by the partnership. At year end the partnership's accounts payable are $140,000 and the assumed debt liability is $180,000. Romanoff opened a $320,000 line of credit but did not draw on the line. To secure the line of credit, each partner had to contribute an additional $40,000. All liabilities are allocated proportionately. The partnership's income is $200,000. Romanoff distributed $100,000 to Natasha. What is her ending outside basis?

Identify each of the following statements as true or false in relation to confidence intervals (CIs). **Note: 0.5 marks will be taken away for each incorrect answer. The minimum score is 0.**

True | False | |
---|---|---|

A 95% CI is a numerical interval within which we are 95% confident that the true mean μ$\mu $ lies. | ||

A 95% CI is a numerical interval within which we are 95% confident that the sample mean x¯¯¯$\overline{x}$ lies. | ||

The true mean μ$\mu $ is always inside the corresponding confidence interval. | ||

For a sample size n=29$n=29$, the number of degrees of freedom is n=30$n=30$. | ||

If we repeat an experiment 100 times (with 100 different samples) and construct a 95% CI each time, then approximately 5 of those 100 CIs would not$not$ contain the true mean 𝜇. |
