Light waves with two different wavelengths, 632 nm and 474 nm, pass simultaneously through a single slit whose width is 6.59 10-5 m and strike a screen 1.13 m from the slit. Two diffraction patterns are formed on the screen. What is the distance (in cm) between the common center of the diffraction patterns and the first occurrence of a dark fringe from one pattern falling on top of a dark fringe from the other pattern?

a.    The critical value is 3.841. Since the χ2test statistic is above the critical value, we fail to reject the null hypothesis. There is insufficient evidence to claim that participation in the host home program and signs of depression are dependent on each other.

b.    The critical value is 0.004. Since the χ2test statistic is above the critical value, we reject the null hypothesis. There is sufficient evidence to reject the claim that participation in the host home program and signs of depression are independent of each other.

c.    The critical value is 3.841. Since the χ2test statistic is above the critical value, we reject the null hypothesis. There is sufficient evidence to reject the claim that participation in the host home program and signs of depression are independent of each other.

d.    The critical values are -3.841 and 3.841. Since the χ2is outside of the critical value range, we fail to reject the null hypothesis. There is insufficient evidence to claim that participation in the host home program and signs of depression are dependent on each other.

e.    The critical value is 7.815. Since the χ2is above the critical value, we reject the null hypothesis. There is sufficient evidence to reject the claim that participation in the host home program and signs of depression are independent of each other.

Like Bill, in question 3 above, Scott has bought a house in Canberra, borrowing the same amount, and on the the same terms. Scott’s bank, however, offers an ‘interest offset’ account facility with the loan. Like Bill, Scott’s first payment is on 19 March 2020. On the day Scott takes the loan of $600 000 out (19 March 2019), Malcolm gives Scott $100 000. Scott immediately puts the money into his interest offset account. This account also earns 3.5% p.a. (compound interest). Over the term of the loan Scott does not put any more money into the interest offset account. The interest offset account pays interest annually, and its first payment will be on 19 March 2020.

a. Draw a cash flow diagram, from Scott’s perspective, that describes the actions of his interest offset account. Scott’s interest offset account pays its interest payments to Scott’s loan.

b. What is the amount of Scott’s total loan repayment on 19 March 2020?

c. Show that Scott can make the total repayments calculated in part b for only 25 years, and that in the 26th year Scott will only pay a reduced value, how did you reach this value?
