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. |

Solve the following differential equation dx/dy=-[(4y2+6xy)/(3y2+2x)]

The velocity distribution for laminar flow between parallel plates is given by:

$\frac{u}{{u}_{max}}=1-{\left(\frac{2y}{h}\right)}^{2}$

where h is the distance separating the plates and the origin is placed midway between the plates. Consider a flow of water at ${15}^{\circ}C$ , with ${u}_{max}=0.30\frac{m}{sec}$ and $h=0.50\text{}mm$ . Calculate the shear stress on the upper plate and give its direction.In August 2013, E*TRADE Financial was offering only 0.05% interest on its online checking accounts, with interest reinvested monthly. Find the associated exponential model for the value of a $5000 deposit after "t" years. Assuming that this rate of return continued for 7 years, how much would a deposit of $5000 in August 2013 be worth in August 2020? (Answer to the nearest $1. )
