Answer: 253°F
Step-by-step explanation:
Given the following :
Temperature in Antarctica = - 121 Fahrenheit
Temperature in Sahara desert = 132 Fahrenheit
Number of degrees in which Sahara desert is warmer than Antarctica :
(temperature in Sahara desert - temperature in Antarctica)
= ( 132°F - (-121°F))
= (132°F + 121°F)
= 253°F
Sahara Desert is 253°F warmer
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)
Answer:
20%
