Step-by-step explanation:
Total heads = 10
Total legs = 26
Cat = 4 legs
Birds = 2 legs
------------------------------------
Assumed all birds :
------------------------------------
Total legs = 10 x 2 = 20
------------------------------------
Difference in legs :
------------------------------------
26 - 20 = 6
------------------------------------
Difference in legs between the two animals:
------------------------------------
4 - 2 = 2
------------------------------------
Find number of cats :
------------------------------------
6 ÷ 2 = 3
------------------------------------

formula of std error:


Point differential estimation =

For 90 percent t= 1.860 Cl & 8 df
error of margin E = 

Lower bound =mean difference -E=0.461
Upper bound = mean difference+ E=7.206
In the above 90% confidence interval were the population mean= (0.461 , 7.206)
