A biologist captures birds using a series of mist nets placed throughout a private reserve. They place 15 nets into 3 different areas: Orchard, Forest, and Grazing Land. For 3 months, the biologist records the number of birds that were caught in the net and whether or not they were migrating. Following the field season, the biologist begins analyzing the data in R. They want to see if there are any significant differences in the number of migrant birds caught between the 3 areas.(a) What type of variable is the number of migrant birds (continuous/categorical)?(b) What type of variable is area type (continuous/categorical)? (c) What statistical test would you use to analyze this type of data? State your null and alternative hypotheses.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
