A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If
Ganezh [65]

Answer:

A)

Note that              

             

Lower Bound = X - z(alpha/2) * s / sqrt(n)              

Upper Bound = X + z(alpha/2) * s / sqrt(n)              

             

where              

alpha/2 = (1 - confidence level)/2 =    0.025          

X = sample mean =    1723.4          

z(alpha/2) = critical z for the confidence interval =    1.959963985          

s = sample standard deviation =    89.55083319          

n = sample size =    30          

             

Thus,              

             

Lower bound =    1691.355235          

Upper bound =    1755.444765          

             

Thus, the confidence interval is              

             

(   1691.355235   ,   1755.444765   ) [ANSWER]

Write the explicit rule,
meriva

Answer:

a_{n} = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

a_{n} = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12
