Asample of 25 cereal boxes of granola crunch, a generic brand of cereal, yields a mean (x¯) weight of 1.02 pounds. the goal is to construct a 95% confidence interval for the mean weight (µ) of all cereal boxes of granola crunch. assume that the weight of cereal boxes is normally distributed with a population standard deviation (σ) of 0.03 pounds.

1.01 < µ < 1.03

Step-by-step explanation:

We want to construct a 95% confidence interval.  Our sample size is 25, so we use a t-value.  The degrees of freedom are 24 (always one less than the sample size).  

The t-value we get is:  2.064

We have:

x = 1.02

σ = 0.03

See the attached photo for the construction of the confidence interval...

tigers

step-by-step explanation:

cougars 12/10 (12-10 = 2)

bobcats 20/10 (20-10 =10)

bulldogs 8/5 (8-5 =3)

tigers 3/5 (3-5 =-2)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
