VARVARA [1.3K]

Answer:

There are 7123 boxes of ice cream left in the factory

Step-by-step explanation:

Initially produced in factory : 6911 boxes

135 boxes are sold, so the factory now has 6911 - 135 = 6776

347 more boxes are produced, so we add this number to what there was in the factory: 6776 + 347 = 7123

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

$\= x - E < \mu$

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

=> $13.4< \mu < 13.8$
