Answer:
8 × 4.52 = 36.16
Step-by-step explanation:
We have given expression:
8 × 4.52
We have to find the product of expression.
8 × 4.52
8 × 4.52 = 36.16
36.16 is the product of the given expression.
We completed our question.

Step-by-step explanation:
Answer:
the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)
Step-by-step explanation:
since the variance S² of the batch follows a normal distribution , then for a sample n of 20 distributions , then the random variable Z:
Z= S²*(n-1)/σ²
follows a χ² ( chi-squared) distribution with (n-1) degrees of freedom
since
S² > 3.10 , σ²= 1.75 , n= 20
thus
Z > 33.65
then from χ² distribution tables:
P(Z > 33.65) = 0.02020
therefore the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)
