Asurvey of 85 families showed that 36 owned at least one dvd player. find the 99% confidence interval estimate of the true proportion of families who own at least one dvd player. place your limits, rounded to 3 decimal places, in the blanks. place the lower limit in the first blank

Step-by-step explanation:

The confidence interval for population mean is given by :-

, where is the sample proportion, n is the sample size , is the critical z-value.

Given : Significance level :

Sample size : n= 85

Critical value :

Sample proportion:

Now, the  99% confidence level will be :

Hence, the  99% confidence interval estimate of the true proportion of families who own at least one DVD player is  

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
