s  = sample standard deviation = $260 n = sample size = 35 {five-week} So, 95% confidence interval for average daily revenue, is given by; P(-2.032 < < 2.032) = 0.95 P(-2.032 < < 2.032) = 0.95 P(-2.032 * < < 2.032 * ) = 0.95 P(X bar - 2.032 * < < X bar + 2.032 * ) = 0.95 95% confidence interval for = [ X bar - 2.032 * , X bar + 2.032 * ] = [ 1080 - 2.032 * , 1080 + 2.032 * ] = [ 990.70 , 1169.30 ] No, the manager is not correct based on the fact that the coffee and pastry strategy would lead to an average daily revenue of$1,200 because the calculate 95% confidence interval does not include value of $1200. Therefore, the store manager believe is not correct. ### Final answer: The 95% confidence interval for the store's average daily revenue is calculated to be approximately ($993.97, $1166.03). Since$1200 is outside this interval, the manager's belief that the coffee and pastry strategy will lead to an average daily revenue of $1200 is not backed by this confidence level. ### Explanation: In the field of statistics, a confidence interval (CI) is a type of interval estimate that is used to indicate the reliability of an estimate. The method for calculating a 95% confidence interval for the average daily revenue involves the sample mean, the standard deviation, and the z-score associated with a 95% confidence level, which is approximately 1.96. Let's use the provided data to calculate: • Calculate the standard error by dividing the standard deviation by the square root of the sample size. Here, the standard deviation is$260, and the sample size is 5 weeks * 7 days/week = 35 days. So, the standard error is $260 / sqrt(35) =$43.89.
• Multiply the standard error by the z-score to get the margin of error. So, $43.89 * 1.96 =$86.03.
• Calculate the lower and upper bounds of the 95% confidence interval by subtracting and adding the margin of error from/to the sample mean. So, ($1080 -$86.03, $1080 +$86.03) = ($993.97,$1166.03).

The range of this 95% confidence interval is from $993.97 to$1166.03. This means we are 95% confident that the true average daily revenue lies within this interval. Since $1200 lies outside this interval, the manager's belief is not supported by this confidence interval. ### Learn more about Confidence Interval here: brainly.com/question/34700241 #SPJ3 Find the hypotenuse c of the right triangle a= 6 2/3, b=7 ### Answers Answer: 29/3 Step-by-step explanation: A^2= 400/9 B^2= 49 C^2= 841/9 C= sqr(c^2) = 29/3 or 9 2/3 The hypotenuse would be 9 2/3 Using the Pythagorean Theorem you do 6 2/3 squared + 7 squared 93 4/9 then you find the square root And it leaves you with 9 2/3 Please help 30 points plus brainlyist who does firstDetermine which expressions can be simplified further, and which cannot.

A vertex is where two non parallel lines meet.For example a triangle has 3 vertex.We can also say that vertex is a point where two non parallel lines meet to form an angle. According to the given question the best description of adjacent angle is that they share a side. We can say that adjacent angles are those angles which are placed next to each other. Adjacent angle also share a common vertex but they do not overlap each other. learn more about vertex here : brainly.com/question/12563262 #SPJ2 Answer: The correct answer to this would be D, adjacent angles share a side.

Step-by-step explanation:

HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:

5^2 = 5 x 5

aka, 25.

You can use this to check each of the answers in your formula, like this:

if x=6, then:

x^2 < 100

6 x 6 = 36

36 < 100
