A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. The mean is found to be 13.6
dimaraw [331]

Answer:

The confidence interval is  13.4<  \mu < 13.8

Step-by-step explanation:

From the question we are told that

   The sample  mean is \= x  =  13.6

     The standard deviation is \sigma =  1.9

     The sample  size is  n  =  189

given that the confidence level is  85% then the level of significance is mathematically represented as

            \alpha = (100 - 85 )\%

            \alpha  =  0.15

Next we obtain the critical value  of \frac{\alpha }{2} from the normal distribution table  the value  is  

      Z_{\frac{\alpha }{2} } =  1.44

Generally the margin of error is mathematically represented as

        E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma}{\sqrt{n} }

=>     E = 1.44*  \frac{1.9}{\sqrt{189} }

=>     E = 0.1990

The  85%  confidence interval is mathematically represented as  

        \= x  - E <  \mu

=>      13.6- 0.1990 <  \mu <  13.6+ 0.1990

=>      13.4<  \mu < 13.8

Each T-shirt sells for $8, and each long-sleeve shirt sells for $11. The swim team collected $310 for the 35 shirts that were so
Nonamiya [84]

Answer:

Number of T shirt sold = 25

Number of long-sleeve shirt sold = 10

Option A is the correct answer.

Step-by-step explanation:

Let the number of T shirt be t and long-sleeve shirt be s.

We have cost of T shirt = 8$ and cost of long-sleeve shirt = 11 $.

Total number of shirts sold = 35

                 t + s = 35    -----------------------Equation 1

Dollar collected = 310 by selling 35 shirts = 310 $

                 8 t + 11 s = 310    -----------------------Equation 2

Equation 1 x 8

                8 t + 8 s = 8 x 35 = 280    -----------------------Equation 3

Equation 2 - Equation 3

            8 t + 11 s - 8 t - 8 s = 310 - 280 = 30

                     3 s = 30

                        s = 10

Substituting in equation 1

                t + 10 = 35

                t = 25

Equations are 8t + 11s = 310 and t + s = 35

Number of T shirt sold = 25

Number of long-sleeve shirt sold = 10

Option A is the correct answer.
