katen-ka-za [31]

Answer:

Larger sample size gives less std error and hence test statistic is larger.

Step-by-step explanation:

Given that a newspaper  is conducting a statewide survey concerning the race for governor. The newspaper will take a simple random sample of n registered voters and determine X = the number of voters that will vote for the Democratic candidate. Is there evidence that a clear majority of the population will vote for the Democratic candidate

Group        I   II

Success    640 64

Total   1200 120

p 0.533333333 0.533333333

q 0.466666667 0.466666667

se 0.014401646 0.045542003

p diff 0.033333333 0.033333333

Z 2.314550249 0.731925055

p      0.01           0.233

we find that though p is the same, std error is very small for larger sample size thus making z statistic much bigger.  So we get p value less than 0.05 whereas for 120 sample size, std error is large so Z statistic is small thus making p value to accept null hypothesis

Help pleaseeeeee thanks i hope u have a good day
VikaD [51]

Answer:

12825$

Step-by-step explanation:

1 yard = 3 ft

we can convert each of the lengths from ft to yards

240 ft = 80 yards

285 ft = 95 yards

450 ft = 150 yards

150+150+95+80 = 475 yards

1 yard of fencing costs 27$ so we are going to multiply that by the total yards

475*27=12825$
