Question 1
(i)
(a)Is there a relationship mingled with the continuance of time, in transactions, of the eruptions of Old Faithful Geyser in Yellowstone content Park and the intervals, in minutes, between the eruptions?
(b)The selective information in circumvent 8 are secondary as it has been sourced by soul else. The selective information would be primary if I had sourced the data myself.
(ii)
(a) Scatterplot attached (appendix 1)

(b) A scatterplot is an easy way to visualize paired data and determine if there is any relationship between the twain sets of data. Viewing the data in graph form give notice make it easier to compare the relationship than in a panel form.

(iii)

(a) The scatterplot data does suggest that the longer the eruption the longer the intervals between the eruptions for this lineamenticular set of data. You can see there is a cluster of eruptions between 4 and 5 minutes with a higher level of intervals between the eruptions. The longest eruption of 5.1 minutes also had the longer interval between the next eruptions of 91 minutes.

(b) The data cannot prove conclusively that the intervals between eruptions are a direct result of the duration of an eruption because the data is for much(prenominal) a short period of time, only eleven successive eruptions. To prove any true link further data would need to be collected and different times of the sidereal day and different times of the year.





(iv)

The data was being analysed in part (ii) (a). This is when the data was used to draw the scatterplot; thus being able-bodied to analysis the plot produced.

The data was being interpreted in part (iii) both (a) and (b). This is when conclusions from the data can be wasted and results interpreted.

Question 2

(i)

(a) From the map the grid bearing from Backtor Bridge to Hollins cut across is about 190?.
(b) Find the value of M in the year 2009. Using the formula M = 5 - Y6 as follows:
1994 to 2009 = 15 years therefore M = 5 - 156 = 5 2.5 = 2.5
The formula predicts that magnetic...If you want to get a full essay, rove it on our website: Orderessay
