Answer:
D
Step-by-step explanation:
11.7..... rounded is 12
therefore, √137 is closer to 12
Answer:
T-shirts = t
Price = 8.25
Coupon = - 5.00
p is total price.
t is number of t-shirts.
Function:
p = $8.25t - $5.00
How much would you pay during Bargain Days for 11 shirts?
t = 11
p = 8.25(11) - 5.00
p = 90.75 - 5.00
p = $85.75

Answer:
A. A boxplot of the data has multiple large outliers.
D. A boxplot of the data shows a very slight skew.
Step-by-step explanation:
A) The normal distribution does not have outliers. The outliers are any point outside the 3σ interval which 99.7% of the data. The 0.3% data would not be outliers.
B) YEs the mean and median of the normal distribution are nearly equal. AS it is asymmetrical.
C) When the sample standard deviation is large the data is spread about the mean. The normal distribution is flatter and wider
D) The normal distribution is never skewed.If one end is longer then the distribution is not assymmetric and the normal distribution asymmetric meaning half is the mirror reflection of the other half.
So A and D indicate circumstances where he not be safe to use a t procedure.
