The histogram shows a city’s daily high temperatures recorded for four weeks. A graph shows temperature (degrees Fahrenheit) the horizontal axis numbered 0 to 65 and number days on the vertical axis is numbered 1 to 5. 1 day was 0 to 5 degrees. 0 days were 5 to 10 degrees. 1 day was 10 to 15 degrees. 0 days were 15 to 20 degrees. 1 day was 20 to 25 degrees. 3 days were 25 to 30 degrees. 2 days were 30 to 35 degrees. 5 days were 35 to 40 degrees. 5 days were 40 to 45 degrees. 2 days were 45 to 50 degrees. 5 days were 50 to 55 degrees. 3 days were 55 to 60 degrees. 0 days were 60 to 65 degrees. Which phrase describes the shape of the temperature data? symmetrical left-skewed right-skewed normal

b. left- skewed

Step-by-step explanation:

edge 2020

The answer is (B) Left Skwed

Step-by-step explanation:

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
