Answer:
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 29.5
Standard deviation r = 5.2
Number of samples n = 59
Confidence interval = 90%
z-value (at 90% confidence) = 1.645
Substituting the values we have;
29.5+/-1.645(5.2/√59)
29.5+/-1.645(0.676982337100)
29.5+/-1.113635944529
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
XD LOL can i have brainliest
If Jana wins the contest, she will get two movie tickets, and if she gets two movie tickets, she will take her mother to the movies.
If you think about this deductively, and if you have the knowledge of syllogisms, this won't be difficult to solve.
So, this is the conclusion:
If Jana wins the contest, then she will take her mother to the movies.
This is the conclusion given that if she wins the contest, she will get the tickets she needs to take her mother to the movies. Otherwise, that won't happen.
There were 3 yellow birds. 3 is half of 6 and after Tara bought 1, there would be 2 yellow birds left. Which is 1/3 of 6. Hope this helps!!
You should search it up on Photomath is easier
