For the following data values below, construct a 98% confidence interval if the sample mean is known to be 9.808 and the population standard deviation is 5.013. (round to the nearest thousandth) (type your answer in using parentheses! use a comma when inputing your answers! do not type any unnecessary spaces! list your answers in ascending order! ) for example: (0.45,0.78)

(-19.92, 21.488)

Step-by-step explanation:

given data:

98% confidence interval

Critical value of z at 98% confidence interval is t =  2.33

standard deviation = 5.031

sample mean = 9.808

z statistic to construct 98% confidence interval.

Margin of error = t * standard deviation = 2.33 * 5.013 = 11.680

98% confidence interval of mean is,

(9.808 - 11.68, 9.808 + 11.68)

(-19.92, 21.488)

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
