Refer to the accompanying data set of mean​ drive-through service times at dinner in seconds at two fast food restaurants. const
Anton [14]

Step-by-step explanation:

Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.

The standard error is SE = s/√n = 62.6/√50 = 8.85.

At 95% confidence, the critical value is z = 1.960.

Therefore, the confidence interval is:

180.56 ± 1.960 × 8.85

180.56 ± 17.35

(163, 198)

Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.

The standard error is SE = s/√n = 49.2/√50 = 6.96.

At 95% confidence, the critical value is z = 1.960.

Therefore, the confidence interval is:

152.96 ± 1.960 × 6.96

152.96 ± 13.64

(139, 167)

(1 point) Your velocity is given by v(t)=2t2+8 in m/sec, with t in seconds. Estimate the distance, s, traveled between t=0 and t
yKpoI14uk [10]

Answer:

The estimated distance is 405 meter.

Step-by-step explanation:

Given : Your velocity is given by v(t)=2t^2+8 in m/sec, with t in seconds.

To find : Estimate the distance, s, traveled between t=0 and t=8 ?

Solution :

We have to integrate the function from 0 to 8 to get the distance.

Integrate v(t)=2t^2+8 w.r.t  t,

\int\limits^8_0 {2t^2+8} \, dt

We know, \int\limits {x} \, dx=\frac{x^2}{2}

=[\frac{2t^3}{3}+8t]^8_0

=(\frac{2(8)^3}{3}+8(8))-(\frac{2(0)^3}{3}+8(0))

=(\frac{1024}{3}+64)-(\frac{0}{3}+8(0))

=\frac{1024+192}{3}

=\frac{1216}{3}

=405.33

The estimated distance is 405 meter.
