Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.

morpeh [17]

Answer:

a: 28 < µ < 34

Step-by-step explanation:

We need the mean, var, and standard deviation for the data set.  See first attached photo for calculations for these...

We get a mean of 222/7 = 31.7143

and a sample standard deviation of: 4.3079

We can now construct our confidence interval.  See the second attached photo for the construction steps.

They want a 90% confidence interval.  Our sample size is 7, so since n < 30, we will use a t-score.  Look up the value under the 10% area in 2 tails column, and degree of freedom is 6 (degree of freedom is always 1 less than sample size for confidence intervals when n < 30)

The t-value is: 1.943

We rounded down to the nearest person in the interval because we don't want to over estimate.  It said 28.55, so more than 28 but not quite 29, so if we use 29 as the lower limit, we could over estimate.  It's better to use 28 and underestimate a little when considering customer flow.

Missing fraction<br> blank + 1/16 = 3/2
skad [1K]

Answer: 1/2

Step-by-step explanation:

Let the missing fraction be x

x + 1/16 = 3/2

Make x the subject by subtracting both sides by 1/16

x = 3/2 - 1/16

x= 24 - 16/16

= 8/16; divide through by a common value of 8

x = 1/2

I hope this helps.
