A consumer advocacy group suspects that a local supermarket's 10 oz. packages of cheddar cheese actually weigh less than 10 oz. The standard deviation is 0.15 oz. The group took a random sample of 35 such packages and found that the mean weight for the sample was 9.95 oz. Calculate the confidence interval. Don't forget to label. Please go 4 decimal spaces on the error, but 2 on the boundaries.

Step-by-step explanation:

Confidence interval for population mean:

where , = sample mean , = population standard deviation, n= sample size, = Critical z-value.

As per given,

We will find 95% confidence interval for which

Required confidence interval:

Required confidence interval :

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
