Answer: I think it's no, sorry if I can't help
Step-by-step explanation:
Answer:
1) Appliances are connected in parallel
2) Appliances are connected in parallel
3) Appliances are connected in parallel (because in house , appliances are connected in parallel)
4) Advantage :- Such kind of connections assures that even if one or more appliances stops working , the working of other appliances will remain unaffected because in such connections , voltage remains constant
Disadvantage :- Such circuits can draw more power which leads to high bill charges on electricity. Also such connections need more wiring.
Answer:
90% confidence interval for the true mean weight of orders is between a lower limit of 103.8645 grams and an upper limit of 116.1355 grams.
Step-by-step explanation:
Confidence interval for true mean weight is given as sample mean +/- margin of error (E)
sample mean = 110 g
sample sd = 14 g
n = 16
degree of freedom = n - 1 = 16 - 1 = 15
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 15 degrees of freedom and 10% significance level is 1.753
E = t × sample sd/√n = 1.753×14/√16 = 6.1355 g
Lower limit of sample mean = sample mean - E = 110 - 6.1355 = 103.8645 g
Upper limit of sample mean = sample mean + E = 110 + 6.1355 = 116.1355 g
90% confidence interval is (103.8645, 116.1355)
